Answer 1

I haven't used it myself, but iSpeech has an Android SDK for both text to speech and voice recognition. Their voices sound pretty good compared to a lot of the others, so they may be worth a try. They also seem to allow for direct API access.

Answer 2

Look at this sample code for some code that asks a question using TextToSpeech and then uses SpeechRecognition to check if the answer was correct.

Answer 3

dude your question is not clear... you are looking for voice regonisation application(i.e) accepts user input in voice (or) application which voice out the options (i.e) Text to speech TTS? if you are looking for some text to speech application then you can look into this sample http://developer.android.com/resources/samples/TtsEngine/index.html

else look at other examples given in other answers...

Answer 4

There is no easy option to match speech. I guess you'll have to match loudness, frequency and length of the answer with your database.

Of course you could try Google's Voice Recognition API (per Intent: http://developer.android.com/reference/android/speech/RecognizerIntent.html)

Answer 5

Try google speech/voice recongnition. Some examples: http://developer.android.com/resources/articles/speech-input.html and http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/app/VoiceRecognition.html
