Hello I really enjoy your videos. Can I get the tutorials on how to setup vscode for flutter

Hi, thank you for this video! I was wondering what is the use case for this kind of app with this plugin? At the beginning, I wanted my app to have this speech-text functionality, so I was looking for tutorial and trying it in my app. But then I realized our phone already has a button on the bottom-right ride of the keyboard that can record voice/speech and show it to Text field, so if we just have a text field in the app, user can still use speech for inputting text, and in this way, if any text is wrong, you can modify the text with keyboard, so can you tell me why we use this plugin? what are practical usage of this? Thank you!

How can I edit the text in case I make a mistake? and how can I put it in a textformfield? help me please great video!!

thanks for the video, is there a way to get word confidence score.

brilliant video. Short precise and a GREAT way to ask users to subscribe. Almost played to perfection. i only have one question... where is that variable "val" coming from? can you explain plz?

fan!

First OF ALL my appreciated for that video awesome! but mic of simulator don't recognized mic how to fix ?

Hello , great tutorial still. I wonder, Can we add this a punctation ?

Great

Thanks very much for the video. How can I do this in the form of constant listening? Or how can I run it in the background as an assistant application? Thank you again.

✔✔✔ Greetings, thanks for sharing your knowledge, I don't know if you know any method to navigate between screens using voice. If possible please provide a tutorial on how to do it. Thank you!

Wow. cool

Make a video on how to use Text To Speech using google api voices please.

Can we use another audio input than a microphone? I need to connect to videos or radio audio files.

Thank you so much for this sir. Can you please help me understand why a little pause in talking stop the recording ?

With Flutter you could create the opposite of this text app Means we are adding text output is audio

I just want to know what is the meaning of the confidence value, what is used for?

were planning to create app like this but not in english language

Will you make video on Torrent Search Api with Flutter

Hey mate .... When it converted speech to text then we can save those texts in local so that we can see those texts letter ? Bt how to save those spoken texts in local storage ? Love from INDIA 🇮🇳

Is their a way to save the spoken text in a document inside firestore? thanks

hey great tutorial, works neatly. Is there a way to trigger the voice recoginition automatically so the user does not have to press a button at all? Similiar to amazons "hey alexa".

Can we store this text somewhere or copy maybe?

how to add a list of words which need to be highlighted?

Great Help but small problem - I see a red screen for 1 sec once i press the mic button and then it displayes the speech to text. any idea why a red screen. 2) the mic turns off after 2 seconds automatically in android but the avtarglow dosen't.

It will never enter into the else block, then how isListening will be set to False.

hello marcus, if i listening then i pause first, and I want to continue the text again, how is that?

Is there a way to make it continues ? It works but if the user doesn't speak after a few second then the app wont listen to their speech anymore.

Hi,how we can change language? Is it possible?

Hey! If I would like to use a .wav file, and convert it to text, could use this API or would I need to go down another route?

Can't we save that text?? Is it possible??

how do we save the text which is converted from speech recently to firebase and then reflect it back again ? as I want to save it for my notes and store it in the firebase storage and display the notes in the application itself.......thank you in advance

Could you please show us how to make this app support Arabic voice recognition?

Its works well but what if i wanted to increase the duration of the _islistening do I put it at the duration at the end of the val.confidence or at the beginning of the islitening false ?

Hi is there any offline one ?

I am getting dart analysis error that "the named parameter ' visualDensity' isn't defined" How do i solve this

How can I make it run everytime in back end ?

great tutorial 👍🏼 i have a question, is the voice input added into an array ? if not, in which one line indicates the result (voice input) because i want use the input to send to another API ?

Hey man i downloaded it from the github repository and it didn't work as it should,, it showed me the red widget error you talked about. Also than words would apear but not the entire chat only the word you just spoke. Also the Mic icon didnt reset itself when you finished talking and you had to double click the mic icon to talk again. Idk maby this happend becouse the package versions or libraries have updated and work differently somehow. Anyway after some hours of tuning i finally got it to work properly. So for anyone whose code didn't work try mine : The main.dart : import 'package:avatar_glow/avatar_glow.dart'; import 'package:flutter/material.dart'; import 'package:highlight_text/highlight_text.dart'; import 'package:speech_to_text/speech_to_text.dart' as stt; import 'dart:async'; void main() { runApp(MyApp()); } class MyApp extends StatelessWidget { @override Widget build(BuildContext context) { return MaterialApp( title: 'Flutter Voice', debugShowCheckedModeBanner: false, theme: ThemeData( primarySwatch: Colors.red, visualDensity: VisualDensity.adaptivePlatformDensity, ), home: SpeechScreen(), ); } } class SpeechScreen extends StatefulWidget { @override _SpeechScreenState createState() => _SpeechScreenState(); } class _SpeechScreenState extends State { final Map _highlights = { 'flutter': HighlightedWord( onTap: () => print('flutter'), textStyle: const TextStyle( color: Colors.blue, fontWeight: FontWeight.bold, ), ), 'voice': HighlightedWord( onTap: () => print('voice'), textStyle: const TextStyle( color: Colors.green, fontWeight: FontWeight.bold, ), ), 'subscribe': HighlightedWord( onTap: () => print('subscribe'), textStyle: const TextStyle( color: Colors.red, fontWeight: FontWeight.bold, ), ), 'like': HighlightedWord( onTap: () => print('like'), textStyle: const TextStyle( color: Colors.blueAccent, fontWeight: FontWeight.bold, ), ), 'comment': HighlightedWord( onTap: () => print('comment'), textStyle: const TextStyle( color: Colors.green, fontWeight: FontWeight.bold, ), ), }; stt.SpeechToText _speech; Timer _timer; bool available; bool _isListening = false; String _text = 'Test'; String _displaytext = 'Hi this is Voice Recognition ,, you said:'; double _confidence = 1.0; @override void initState() { super.initState(); _speech = stt.SpeechToText(); } @override Widget build(BuildContext context) { return Scaffold( appBar: AppBar( title: Text('Confidence: ${(_confidence * 100.0).toStringAsFixed(1)}%'), ), floatingActionButtonLocation: FloatingActionButtonLocation.centerFloat, floatingActionButton: AvatarGlow( animate: _isListening, glowColor: Theme.of(context).primaryColor, endRadius: 75.0, duration: const Duration(milliseconds: 2000), repeatPauseDuration: const Duration(milliseconds: 100), repeat: true, child: FloatingActionButton( onPressed: _listen, child: Icon(_isListening ? Icons.mic : Icons.mic_none), ), ), body: SingleChildScrollView( reverse: true, child: Container( padding: const EdgeInsets.fromLTRB(30.0, 30.0, 30.0, 150.0), child: TextHighlight( text: _displaytext, words: _highlights, textStyle: const TextStyle( fontSize: 32.0, color: Colors.black, fontWeight: FontWeight.w400, ), ), ), ), ); } void _error() { available = false; _speech.stop(); _timer = new Timer(const Duration(milliseconds: 1000), () { setState(() { _isListening = false; }); }); } void _listen() async { if (!_isListening) { available = await _speech.initialize( onStatus: (val) => print('onStatus: $val'), onError: (val) { _error(); print('onError: $val');}, ); if (available) { setState(() => _isListening = true); _speech.listen( onResult: (val) => setState(() { _text = val.recognizedWords; if (val.hasConfidenceRating && val.confidence > 0) { _confidence = val.confidence; _displaytext += " ${_text}"; } else { setState(() {_isListening = false;}); } }), ); } } else { setState(() {_isListening = false;}); _speech.stop(); } } }

Is there any reason why right before i talk it goes to the red screen error and then quickly fixes itself and shows the text? Also, my emulator is not nearly as fluid as yours but my machine is a monster. Why is this app lagging so bad?

will this work in offline/no internet mode?

Hi Marcus, thank you so much for the awesome contents! I was able to create the app and it works but I'm keep getting the following error in the console "RangeError (index): Invalid value: Valid value range is empty: -1" Any idea why I'm getting this error?

What is the intro song called?

Code runs without errors, but I get a message on my phone that flutter_voice has stopped. I enabled microphone permissions for flutter_voice, but that was not the problem. Does anybody have any ideas? I compared my AndroidManifest.html to your archived file and they are the same, but mine displays the error warnings in the top right corner of the manifest window.

After cloning and trying it out on Simulator, why 50% words are not converted, I deliberately slowed down speech and still not working ? Anyone else had same issue?
