I was going to implement a speaker verification app for Android, and was wondering if there would be a way to get the voice features (MEL Coefficients) from the Android's Speech Recognition module?
Please note that speaker verification is slightly different than speech recognition, so that's why I'm not using the speech recognition directly.
No, you can not compute MFCC from audio stream with Android API. You can use external library for that, for example CMUSphinx
You can also try existing Java-only libraries for voice verification for Android like
Recognito

I am working on a project on "Home Automation" system with Android app and Microcontroller , connecting them through Bluetooth module. I have incorporated "speech to text" for voice commands. Although , it works well with the built-in google speech recognition api. All I need is a continuous speech recognition and without the google voice pop-up.
I have seen a similar app on playstore "speechnotes" that works exactly i wish to develop. And it works totally offline.
You should try Droid Speech it supports continuous voice recognition and also will work offline if the speech package for the required language is installed in the device.
Setting the library in your project is very simple and with a few lines of code you can easily start using speech recognition.
An example,
Add the below in your Gradle file,
compile 'com.github.vikramezhil:DroidSpeech:v2.0.3’
In your Activity,
DroidSpeech droidSpeech = new DroidSpeech(this, null);
droidSpeech.setOnDroidSpeechListener(this);
To start droid speech to listen to user voice call the method,
droidSpeech.startDroidSpeechRecognition();
The speech result will be triggered at,
#Override
public void onDroidSpeechFinalResult(String finalSpeechResult)
{
// Do whatever you want with the speech result
}
I'm using Java to read and play some real time audio streams such as the voice from radio station.
I have the real time web address like this one and it can be played in a web browser.
How can I play it using Java language?
Thanks.
MP3SPI is a Java Service Provider Interface that adds MP3 (MPEG 1/2/2.5 Layer 1/2/3) audio format support for Java Platform. It supports streaming, ID3v2 frames, Equalizer etc. It is based on JLayer and Tritonus Java libraries.
You can use this library MP3 SPI for Java Sound , and its documentation here.

I am trying to stream a video in app using the native player for android. But when trying to stream a link with "rtmpe://" it doesn't work. Can anyone guide me on how to play this? So far I have only seen solutions of iOS. I want to play this without using external Apps.
Check supported media formats for Android here. Not all protocols work on android.
Could anyone tell me, Where can i find api for waveTable syntesis on android?
Or maybe i can use one of C++ waveTable synth libraries on android through JNI?
MediaPlayer and JetPlayer does not fit for this task.
I need to play MIDI, but with good soundbanks and be able to change soundbanks on user request.
AFAIR there's no API for this in SDK. If you want to play midi on android use MediaPlayer to do the playback (it does support midi files)
I am working in speech recognition in android. I want to use java speech api . Can i use that for android or there is a better api for android ?????
note: I want to match two audio file
Todo speech recognition the RECOGNIZE_SPEECH Intent is probably the easiest way. Check the introduction to Speech Input for more details.
