is implemented, all  you need is the runtime.

    tcross> Although I've never got around to it, mbrola voices

    tcross> festival. Voices from http://www.cepstral.com can
    tcross> also be used with festival - they had a perl script
    tcross> on their website that would allow you to import a
    tcross> cepstral voice into festival. Cepstral voices are
    tcross> good quality, but they lose quality significantly at
    tcross> higher voice speaking rates. They are commercial
    tcross> voices which you have to pay for, but they do have a
    tcross> number of different languages available.
    tcross> 
    tcross> IMO by far the best software TTS for emacspeak is
    tcross> ViaVoice, which you can purchase from
    tcross> http://www.wizzardsoftware.com. However, you have to
    tcross> purchase the SDK and it costs over $300US.
    tcross> 
    tcross> Second best for quality of speech is the software
    tcross> dectalk. However, this TTS engine does crash
    tcross> regularly under emacspeak (it works reliably under
    tcross> speech dispatcher, but speech dispatcher is using it
    tcross> in its most basic way and does not try to use the
    tcross> in-line voice control codes emacspeak uses for voice
    tcross> locking etc). The software dectalk is available from
    tcross> http://www.fonix.com for about $100US.
    tcross> 
    tcross> I used the softwar dectalk for quite some time and
    tcross> managed to live with the regular crashes - all you
    tcross> need to do is a C-e C-s when the TTS stops working
    tcross> and verything is restarted. Although a bit annoying,
    tcross> it provides good voice quality at high speaking

    tcross> emergency backup TTS if I don't have a hardware
    tcross> synthesiser for backup.
