Speech_To_Text In Flutter is used to convert voice or speech into the form of text or converting spoken words into written texts.
Before we start, have a look at flutter app development services from mobikul.
In this blog, we are using three packages to completely demonstrate the speech to text in a flutter.
Here, we are also going to use the confidence feature which measures the degree of accuracy for the response.
Step1: Create a flutter project.
Step2: Add the below dependencies in pubspec.yaml file.
|
1 2 3 |
speech_to_text: ^3.1.0 highlight_text: ^0.7.2 avatar_glow: ^1.2.0 |
In order to check the updated version of the dependency click here.
Step3: Now add permission for record voice in AndroidManifest.xml file.
|
1 2 3 |
<uses-permission android:name="android.permission.RECORD_AUDIO" /> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> |
Step4: We should make sure that minSdkVersion must be greater than 21.
|
1 |
minSdkVersion 21 |
Step5: Now start coding for the same.

import 'package:flutter/material.dart'; import 'package:avatar_glow/avatar_glow.dart'; import 'package:highlight_text/highlight_text.dart'; import 'package:speech_to_text/speech_to_text.dart' as speechToText; void main() { runApp(MyApp()); } class MyApp extends StatelessWidget { // This widget is the root of your application. @override Widget build(BuildContext context) { return MaterialApp( debugShowCheckedModeBanner: false, home: MyHomePage(), ); } } class MyHomePage extends StatefulWidget { @override _MyHomePageState createState() => _MyHomePageState(); } class _MyHomePageState extends State<MyHomePage> { speechToText.SpeechToText speech; String textString = "Press The Button"; bool isListen = false; double confidence = 1.0; final Map<String, HighlightedWord> highlightWords = { "flutter": HighlightedWord( textStyle: TextStyle(color: Colors.redAccent, fontWeight: FontWeight.bold)), "developer": HighlightedWord( textStyle: TextStyle(color: Colors.redAccent, fontWeight: FontWeight.bold)), }; void listen() async { if (!isListen) { bool avail = await speech.initialize(); if (avail) { setState(() { isListen = true; }); speech.listen(onResult: (value) { setState(() { textString = value.recognizedWords; if (value.hasConfidenceRating && value.confidence > 0) { confidence = value.confidence; } }); }); } } else { setState(() { isListen = false; }); speech.stop(); } } @override void initState() { super.initState(); speech = speechToText.SpeechToText(); } @override Widget build(BuildContext context) { return Scaffold( appBar: AppBar( title: Text("Speech To Text"), ), body: Column( children: [ SizedBox( height: 10.0, ), Container( child: Text( "Confidence: ${(confidence * 100.0).toStringAsFixed(1)}%", style: TextStyle( fontSize: 20.0, fontWeight: FontWeight.bold, color: Colors.red), ), ), Container( padding: EdgeInsets.all(20), child: TextHighlight( text: textString, words: highlightWords, textStyle: TextStyle( fontSize: 25.0, color: Colors.black, fontWeight: FontWeight.bold), ), ) ], ), floatingActionButton: AvatarGlow( animate: isListen, glowColor: Colors.red, endRadius: 65.0, duration: Duration(milliseconds: 2000), repeatPauseDuration: Duration(milliseconds: 100), repeat: true, child: FloatingActionButton( child: Icon(isListen ? Icons.mic : Icons.mic_none), onPressed: () { listen(); }, ), ), ); } } |
Finally, we can run the code and as a result, we can see the below output.

As per your query, here we are using the speech_to_text package which is used to convert your voice to text and here we also highlighted some of the predefined words. If you want all your spoken text to be highlighted then you might go with the dynamic_text_highlighting package.
Link for dynamic_text_highlighting – https://pub.dev/packages/dynamic_text_highlighting
Thank you

If you are referring the box to the plugin, then you can check out the updated version of the plugin from – https://pub.dev/packages/speech_to_text
Thanks for showing interest in our blog. According to your query yes, you can store & fetch the data inside the firebase. And if you want the same for the spoken words, then you can create a function that converts all spoken words into the text and directly store the text file in the firebase.
