Least Expensive Android Phone for TTS SW Development?

Question

I know many developers ask about the best Android phone for development, but my question is almost opposite: What is the least expensive Android phone that I can get away with TTS (text-to-speech) and ASR (automated-speech-recognition) software development?

To further clarify my question:

1. Do all Android phones support TTS and ASR?
2. Do all Android OS versions support TTS and ASR?
3. If the answer to either of the above is 'No', then which brand/model will provide me with TTS and ASR functionality while minimizing out-of-pocket expense?

Thanks.

Answer 1

Do all Android phones support TTS and ASR?

They should, subject to:

Do all Android OS versions support TTS and ASR?

ASR came in Android 1.5. TTS was added in Android 1.6.

Be careful when dealing with non-phones, though, as they may not have a microphone.
