    Thumbs up Text to Speech (Voice) conversion

    Hi All,

    I am working on j2me. I am developing an application in which I want to convert the Text to Speech (Voice) or Speech (Voice) to Text.

    Is this possible in J2ME with available API?

    How should I start to do this?

    Please reply as early as possible.

    Regards,
    Koustubh.

    Re: Text to Speech (Voice) conversion

    There is Java Speech API (JSR-113), which has been developed specifically for this purpose. Unfortunately it is not yet available on the phones.

    I am not aware of J2ME implementations for either TTS or ASR (Text-to-speech or Automatic Speech Recognition). I would require a lot of work and as you do not have low-level access to the audio devices on the phone, you would have some performance issues. For example, you can only analyze the audio recording after you have stopped recording.

    Regarding it?

    Utilizing JSR-113 on the emulator and test that? (I think you need the reference implementation for that and that does not exist yet, to my understanding)

    Trying out the workaround I briefly described above? In theory possible, but the workaround in general is not really usable because of performance reasons and you would need to do a lot of work to get this working at all...

    Lightbulb Text to Speech (Voice) - Solution

    I have designed that feature for a start-up company:
    Client Server ->
    if TTS:
    ------
    Phone sends text to server.
    Server over J2EE can perform TTS ( there are many APIS, few of them are even free)
    after, an AUDIO file will be replied back to mobile with its audio.

    if ASR:
    -------
    Design a MidLet that records an audio file and send it to a server that will perform ASR and reply back the strings.


    Good Luch,
    Y
