Choose a TTS engine

I would like to buy a TTS voice for my Voicent system. I went to the website Nextup.com, there are too many choices. I would like to have your take on this: Which TTS should we pick?. Do we need to purchase “Text Aloud” as well to have it work with your plug-in?

Yes, Nextup.com has many choices, and some voices offer trial downloads. So it is always a good idea to test it out with the trial version.

You do not need Text Aloud in order to use TTS plug-in.

Could Voicent system support 22hmz file? What’s is the best audio format (mp3, wav, and wma)?

The global telephone network (PSTN) uses the standard PCM 8KHz, 16 bit, mono format. So it is better to choose a 8KHz voice and wave file. Depends on the engine, some 16KHz or 22KHz can generate 8KHz voices also, but that will be extra CPU usages.

What are the requirement for TTS?

Any Microsoft SAPI 5 compliant voices should do. Also, you only need to get a single port engine, since TTS Plug-In will turn a single port engine to a TTS server, allowing simultanuous calls to use the same TTS engine.

The best advice we can give is to try before purchase.
