I want to be able to change the voice in the text to speech API such as change the:
Voice from female to male.
Make the voice more clear
Change the speed of the voice
Please can someone let me know if this is possible.
Thanks.
You can provide your own conversions for specific strings via addSpeech(). There is no documentation for how you can substitute your own text-to-speech engine, though, AFAICT.

I want integrate the algorithm which is used by paytm to speak amount like 20rs done successfully. so i want to implement same functionality can anyone suggest that how i can achieve this with india voice accent in android or kotlin.
You can use speak() method of android.speech.tts.TextToSpeech class
and using the same you can convert a text to speech (audio)
Is it possible to restrict the Google Speech API to only recognize from a given set of words? Alternatively, is it possible to "ban" certain words? If not, is it possible with any other speech API that supports German?
I do know that I can set hint phrases via a speech context. Still it rather recognizes a different word.
As an example, I use the API mostly for the German language. I want to recognize the word "stärker" (which is also listed as a speech context hint), though, the API mostly transcribes it to "Stärke" unless I pronounce the "r" at the end unnaturally strong. So, is it possible to prevent the speech API from transcribing that word, for instance?
Thanks in advance!
No, that's not possible with Google Speech API. I don't know if it's possible with other speech recognition services.
Google speech API supports set of parameters in RecognitionConfig.
There is an optional boolean parameter called "profanityFilter", which filters out profanities.

I have few questions to ask related to Google Speech recognition in Android. I have developed an Android application using Google Speech Recognition online service. Now, to further improve it, I need to know answers for the below questions.
Can I add a "custom dictionary" either in offline recognition or online recognition?
Can I command it to do Grammar based recognition, keyword recognition and keyphrase recognition? Right now it seems like there is no options for such, instead of common recognition.
Can I change the "listen timeout" ? It seems like how much I change, it simply do not work.
It's not possible with Android Speech API, but you can use CMU Sphinx project for all of the above.
This is the correct answer, because I have tried and done it.
Can I add a "custom dictionary" either in offline recognition or
online recognition?
Not possible
Can I command it to do Grammar based recognition, keyword recognition
and keyphrase recognition? Right now it seems like there is no options
for such, instead of common recognition
Can't command it to do grammer based recognition but can detect keywords and keyphrase, you have to write custom code with if-else condition do do that. To do this you actually need detect and convert word by word instead of waiting for the entire sentence is completed by the user and android voice recognition service automatically get closed to give you the result. This is possible and it is known as "mid speech interim"
For keyword recognition see this video
Can I change the "listen timeout" ? It seems like how much I change,
it simply do not work.
No, but you can code it in a tricky way to do continuous recognition. Aboce youtube video does continuous recognition as well. For an application which does the same refer to this link.
or is there any library that I can use?
What I want is to record a audio, and then display the text recognized. Thanks a lot.
Yes, please do a google search next time, http://code4reference.com/2012/07/tutorial-android-voice-recognition/
Alternately, if you want more control you can use SpeechRecognizer, Is there a way to use the SpeechRecognizer API directly for speech input?
I'm using the Speech Recognizer Intent in Android. Is there a way to add your own customized words or phrases to Android's Speech recognition 'dictionary'
No. You can only use the two language models supported.
The built in speech recognition provided by google only supports the dictation and search language models. See http://developer.android.com/reference/android/speech/RecognizerIntent.html and LANGUAGE_MODEL_FREE_FORM or LANGUAGE_MODEL_WEB_SEARCH.
http://developer.android.com/resources/articles/speech-input.html says:
You can make sure your users have the
best experience possible by requesting
the appropriate language model:
free_form for dictation, or web_search
for shorter, search-like phrases. We
developed the "free form" model to
improve dictation accuracy for the
voice keyboard, while the "web search"
model is used when users want to
search by voice
Michael is correct, you cannot change the Language Model.
However, you can use "sounds like" algorithms to process the results from Android and match words it doesn't know.
See my answer here:
speech recognition reduce possible search results
