# Changelog
|
||||
|
||||
## 2.3.0
|
||||
|
||||
### New
|
||||
* new parameter `onDevice` on the `listen` method enforces on device recognition for sensitive content
|
||||
* onSoundLevelChange now supported on iOS
|
||||
* added compile troubleshooting help to README.md
|
||||
* `SpeechToTextProvider` is an alternate and simpler way to interact with the `SpeechToText` plugin.
|
||||
* new `provider_example.dart` example for usage of `SpeechToTextProvider`.
|
||||
### Fix
|
||||
* on iOS handles some conflicts with other applications better to keep speech working after calls for example
|
||||
|
||||
|
||||
## 2.2.0
|
||||
|
||||
### New
|
||||
* improved error handling and logging in the iOS implementation
|
||||
* added general guides for iOS to the README
|
||||
* moved stress testing out of the main example
|
||||
* iOS now defaults to using the speaker rather than the receiver for start /stop sounds when no headphones
|
||||
### Fix
|
||||
* iOS now properly deactivates the audio session when no longer listening
|
||||
* start and stop sounds on iOS should be more reliable when available
|
||||
|
||||
## 2.1.0
|
||||
### Breaking
|
||||
* `listenFor` now calls `stop` rather than `cancel` as this seems like more useful behaviour
|
||||
|
||||
### Fix
|
||||
* Android no longer stops or cancels the speech recognizer if it has already been shutdown by a
|
||||
timeout or other platform behaviour.
|
||||
* Android no longer tries to restart the listener when it is already active
|
||||
* Now properly notifies errors that happen after listening stops due to platform callback rather than
|
||||
client request. See https://github.com/csdcorp/speech_to_text/issues/51
|
||||
|
||||
## 2.0.1
|
||||
### Fix
|
||||
* Resolves an issue with the Android implementation not handling permission requests properly on apps
|
||||
that didn't use the 1.12.x plugin APIs for registration. The permission dialog would not appear and
|
||||
permission was denied.
|
||||
|
||||
|
||||
## 2.0.0
|
||||
|
||||
### Breaking
|
||||
|
||||
* Upgraded to New Swift 1.12 plugin structure, may work with older Flutter version but not guaranteed
|
||||
|
||||
### New
|
||||
|
||||
* the plugin now requests both speech and microphone permission on initialize on iOS
|
||||
* added `debugLogging` parameter to the `initialize` method to control native logging
|
||||
|
||||
### Fix
|
||||
|
||||
* The Android implementation now blocks duplicate results notifications. It appears that at least on some
|
||||
Android versions the final results notification onResults is notified twice when Android automatically
|
||||
terminates the session due to a pause time. The de-duplication looks for successive notifications
|
||||
with < 100 ms between them and blocks the second. If you miss any onResult notifications please post
|
||||
an issue.
|
||||
|
||||
## 1.1.0
|
||||
|
||||
### New
|
||||
|
||||
* error_timeout has been separated into error_network_timeout and error_speech_timeout
|
||||
|
||||
## 1.0.0
|
||||
|
||||
### New
|
||||
* hasPermission to check for the current permission without bringing up the system dialog
|
||||
* `listen` has a new optional `cancelOnError` parameter to support automatically canceling
|
||||
a listening session on a permanent error.
|
||||
* `listen` has a new optional `partialResults` parameter that controls whether the callback
|
||||
receives partial or only final results.
|
||||
|
||||
## 0.8.0
|
||||
|
||||
### New
|
||||
|
||||
* speech recognizer now exposes multiple possible transcriptions for each recognized speech
|
||||
* alternates list on SpeechRecognitionResult exposes alternate transcriptions of voice
|
||||
* confidence on SpeechRecognitionResult gives an estimate of confidence in the transcription
|
||||
* isConfident on SpeechRecognitionResult supports testing confidence
|
||||
* hasConfidenceRating on SpeechRecognitionResult indicates if confidence was provided from the device
|
||||
* new SpeechRecognitionWords class gives details on per transcription words and confidence
|
||||
|
||||
### Fix
|
||||
|
||||
* speechRecognizer availabilityDidChange was crashing if invoked due to an invalid parameter type
|
||||
* Added iOS platform 10 to example Podfile to resolve compilation warnings
|
||||
|
||||
## 0.7.2
|
||||
|
||||
### Breaking
|
||||
|
||||
* Upgrade Swift to version 5 to match Flutter. Projects using this plugin must now switch to 5.
|
||||
|
||||
## 0.7.1
|
||||
|
||||
### Fix
|
||||
|
||||
* Upgrade Kotlin to 1.3.5 to match the Flutter 1.12 version
|
||||
* Upgrade Gradle build to 3.5.0 to match the Flutter 1.12 version
|
||||
* Android version of the plugin was repeating the system default locale in the `locales` list
|
||||
|
||||
## 0.7.0
|
||||
|
||||
### New
|
||||
|
||||
* locales method returns the list of available languages for speech
|
||||
* new optional localeId parameter on listen method supports choosing the comprehension language separately from the current system locale.
|
||||
|
||||
### Breaking
|
||||
|
||||
* `cancel` and `stop` are now async
|
||||
|
||||
## 0.6.3
|
||||
|
||||
### Fix
|
||||
|
||||
* request permission fix on Android to ensure it doesn't conflict with other requests
|
||||
|
||||
## 0.6.2
|
||||
|
||||
### Fix
|
||||
|
||||
* channel invoke wasn't being done on the main thread in iOS
|
||||
|
||||
## 0.6.1
|
||||
|
||||
### Fix
|
||||
|
||||
* listening sound was failing due to timing, now uses play and record mode on iOS.
|
||||
|
||||
## 0.6.0
|
||||
### Breaking
|
||||
|
||||
* The filenames for the optional sounds for iOS have changed.
|
||||
|
||||
### New
|
||||
|
||||
* Added an optional listenFor parameter to set a max duration to listen for speech and then automatically cancel.
|
||||
|
||||
### Fix
|
||||
|
||||
* Was failing to play sounds because of record mode. Now plays sounds before going into record mode and after coming out.
|
||||
* Status listener was being ignored, now properly notifies on status changes.
|
||||
|
||||
## 0.5.1
|
||||
* Fixes a problem where the recognizer left the AVAudioSession in record mode which meant that subsequent sounds couldn't be played.
|
||||
|
||||
## 0.5.0
|
||||
Initial draft with limited functionality, supports:
|
||||
* initializing speech recognition
|
||||
* asking the user for permission if required
|
||||
* listening for recognized speech
|
||||
* canceling the current recognition session
|
||||
* stopping the current recognition session
|
||||
* Android and iOS 10+ support
|
||||
|
||||
Missing:
|
||||
* some error handling
|
||||
* testing across multiple OS versions
|
||||
* and more, to be discovered...

# speech_to_text
|
||||
|
||||
[](https://pub.dartlang.org/packages/speech_to_text) [](https://github.com/csdcorp/speech_to_text/actions?query=workflow%3Abuild)
|
||||
|
||||
A library that exposes device specific speech recognition capability.
|
||||
|
||||
This plugin contains a set of classes that make it easy to use the speech recognition
|
||||
capabilities of the mobile device in Flutter. It supports both Android and iOS. The
|
||||
target use cases for this library are commands and short phrases, not continuous spoken
|
||||
conversion or always on listening.
|
||||
|
||||
## Recent Updates
|
||||
|
||||
The 2.3.0 version adds `SpeechToTextProvider` as a simpler way to interact with the plugin. Checkout
|
||||
the new `provider_example.dart` for intended usage.
|
||||
|
||||
The 2.2.0 version improves audio session handling and start / stop sound playback on iOS.
|
||||
|
||||
*Note*: Feedback from any test devices is welcome.
|
||||
|
||||
## Using
|
||||
|
||||
To recognize text from the microphone import the package and call the plugin, like so:
|
||||
|
||||
```dart
|
||||
import 'package:speech_to_text/speech_to_text.dart' as stt;
|
||||
|
||||
stt.SpeechToText speech = stt.SpeechToText();
|
||||
bool available = await speech.initialize( onStatus: statusListener, onError: errorListener );
|
||||
if ( available ) {
|
||||
speech.listen( onResult: resultListener );
|
||||
}
|
||||
else {
|
||||
print("The user has denied the use of speech recognition.");
|
||||
}
|
||||
// some time later...
|
||||
speech.stop()
|
||||
```
|
||||
|
||||
### Initialize once
|
||||
The `initialize` method only needs to be called once per application session. After that `listen`,
|
||||
`start`, `stop`, and `cancel` can be used to interact with the plugin. Subsequent calls to `initialize`
|
||||
are ignored which is safe but does mean that the `onStatus` and `onError` callbacks cannot be reset after
|
||||
the first call to `initialize`. For that reason there should be only one instance of the plugin per
|
||||
application. The `SpeechToTextProvider` is one way to create a single instance and easily reuse it in
|
||||
multiple widgets.
|
||||
|
||||
## Permissions
|
||||
|
||||
Applications using this plugin require user permissions.
|
||||
### iOS
|
||||
|
||||
Add the following keys to your _Info.plist_ file, located in `<project root>/ios/Runner/Info.plist`:
|
||||
|
||||
* `NSSpeechRecognitionUsageDescription` - describe why your app uses speech recognition. This is called _Privacy - Speech Recognition Usage Description_ in the visual editor.
|
||||
* `NSMicrophoneUsageDescription` - describe why your app needs access to the microphone. This is called _Privacy - Microphone Usage Description_ in the visual editor.
|
||||
|
||||
### Android
|
||||
|
||||
Add the record audio permission to your _AndroidManifest.xml_ file, located in `<project root>/android/app/src/main/AndroidManifest.xml`.
|
||||
|
||||
* `android.permission.RECORD_AUDIO` - this permission is required for microphone access.
|
||||
* `android.permission.INTERNET` - this permission is required because speech recognition may use remote services.
|
||||
|
||||
## Adding Sounds for iOS (optional)
|
||||
|
||||
Android automatically plays system sounds when speech listening starts or stops but iOS does not. This plugin supports playing sounds to indicate listening status on iOS if sound files are available as assets in the application. To enable sounds in an application using this plugin add the sound files to the project and reference them in the assets section of the application `pubspec.yaml`. The location and filenames of the sound files must exactly match what
|
||||
is shown below or they will not be found. The example application for the plugin shows the usage. *Note* These files should be very short as they delay
|
||||
the start / end of the speech recognizer until the sound playback is complete.
|
||||
```yaml
|
||||
assets:
|
||||
- assets/sounds/speech_to_text_listening.m4r
|
||||
- assets/sounds/speech_to_text_cancel.m4r
|
||||
- assets/sounds/speech_to_text_stop.m4r
|
||||
```
|
||||
* `speech_to_text_listening.m4r` - played when the listen method is called.
|
||||
* `speech_to_text_cancel.m4r` - played when the cancel method is called.
|
||||
* `speech_to_text_stop.m4r` - played when the stop method is called.
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### SDK version error trying to compile for Android
|
||||
```
|
||||
Manifest merger failed : uses-sdk:minSdkVersion 16 cannot be smaller than version 21 declared in library [:speech_to_text]
|
||||
```
|
||||
The speech_to_text plugin requires at least Android SDK 21 because some of the speech functions in Android
|
||||
were only introduced in that version. To fix this error you need to change the `build.gradle` entry to reflect
|
||||
this version. Here's what the relevant part of that file looked like as of this writing:
|
||||
```
|
||||
defaultConfig {
|
||||
applicationId "com.example.app"
|
||||
minSdkVersion 21
|
||||
targetSdkVersion 28
|
||||
versionCode flutterVersionCode.toInteger()
|
||||
versionName flutterVersionName
|
||||
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
|
||||
}
|
||||
```
|
||||
|
||||
### Incorrect Swift version trying to compile for iOS
|
||||
```
|
||||
/Users/markvandergon/flutter/.pub-cache/hosted/pub.dartlang.org/speech_to_text-1.1.0/ios/Classes/SwiftSpeechToTextPlugin.swift:224:44: error: value of type 'SwiftSpeechToTextPlugin' has no member 'AVAudioSession'
|
||||
rememberedAudioCategory = self.AVAudioSession.Category
|
||||
~~~~ ^~~~~~~~~~~~~~
|
||||
/Users/markvandergon/flutter/.pub-cache/hosted/pub.dartlang.org/speech_to_text-1.1.0/ios/Classes/SwiftSpeechToTextPlugin.swift:227:63: error: type 'Int' has no member 'notifyOthersOnDeactivation'
|
||||
try self.audioSession.setActive(true, withFlags: .notifyOthersOnDeactivation)
|
||||
```
|
||||
This happens when the Swift language version is not set correctly. See this thread for help https://github.com/csdcorp/speech_to_text/issues/45.
|
||||
|
||||
### Swift not supported trying to compile for iOS
|
||||
```
|
||||
`speech_to_text` does not specify a Swift version and none of the targets (`Runner`) integrating it have the `SWIFT_VERSION` attribute set.
|
||||
```
|
||||
This usually happens for older projects that only support Objective-C. See this thread for help https://github.com/csdcorp/speech_to_text/issues/88.
|
||||
|
||||
### Not working on a particular Android device
|
||||
The symptom for this issue is that the `initialize` method will always fail. If you turn on debug logging
|
||||
using the `debugLogging: true` flag on the `initialize` method you'll see `'Speech recognition unavailable'`
|
||||
in the Android log. There's a lengthy issue discussion here https://github.com/csdcorp/speech_to_text/issues/36
|
||||
about this. The issue seems to be that the recognizer is not always automatically enabled on the device. Two
|
||||
key things helped resolve the issue in this case at least.
|
||||
|
||||
#### First
|
||||
1. Go to Google Play
|
||||
2. Search for 'Google'
|
||||
3. You should find this app: https://play.google.com/store/apps/details?id=com.google.android.googlequicksearchbox
|
||||
If 'Disabled' enable it
|
||||
|
||||
This is the SO post that helped: https://stackoverflow.com/questions/28769320/how-to-check-wether-speech-recognition-is-available-or-not
|
||||
|
||||
#### Second
|
||||
Ensure the app has the required permissions. The symptom for this that you get a permanent error notification
|
||||
'error_audio_error` when starting a listen session. Here's a Stack Overflow post that addresses that
|
||||
https://stackoverflow.com/questions/46376193/android-speechrecognizer-audio-recording-error
|
||||
Here's the important excerpt:
|
||||
>You should go to system setting, Apps, Google app, then enable its permission of microphone.
|
||||
|
||||
### iOS recognition guidelines
|
||||
Apple has quite a good guide on the user experience for using speech, the original is here
|
||||
https://developer.apple.com/documentation/speech/sfspeechrecognizer This is the section that I think is particularly relevant:
|
||||
|
||||
>#### Create a Great User Experience for Speech Recognition
|
||||
>Here are some tips to consider when adding speech recognition support to your app.
|
||||
|
||||
>**Be prepared to handle failures caused by speech recognition limits.** Because speech recognition is a network-based service, limits are enforced so that the service can remain freely available to all apps. Individual devices may be limited in the number of recognitions that can be performed per day, and each app may be throttled globally based on the number of requests it makes per day. If a recognition request fails quickly (within a second or two of starting), check to see if the recognition service became unavailable. If it is, you may want to ask users to try again later.
|
||||
|
||||
>**Plan for a one-minute limit on audio duration.** Speech recognition places a relatively high burden on battery life and network usage. To minimize this burden, the framework stops speech recognition tasks that last longer than one minute. This limit is similar to the one for keyboard-related dictation.
|
||||
Remind the user when your app is recording. For example, display a visual indicator and play sounds at the beginning and end of speech recognition to help users understand that they're being actively recorded. You can also display speech as it is being recognized so that users understand what your app is doing and see any mistakes made during the recognition process.
|
||||
|
||||
>**Do not perform speech recognition on private or sensitive information.** Some speech is not appropriate for recognition. Don't send passwords, health or financial data, and other sensitive speech for recognition.

# speech_to_text_example
|
||||
|
||||
Demonstrates how to use the speech_to_text plugin. This example requires
|

that the plugin has been installed. It initializes speech recognition,
|

listens for words and prints them.

# Launch Screen Assets
|
||||
|
||||
You can customize the launch screen with your own desired assets by replacing the image files in this directory.
|
||||
|
||||
You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.
