Kazoo uses an external API service [ispeech.org] when the functionality is called for.
- You will need to signup for an account and pay real money(TM) and comissions.
-
The TTS speech quality from ispeech.org is truely awesome.
- Think Star Trek Voice API.
-
If you buy the service and try the languages and so forth it works really well.
- Everybody should be impressed with the TTS.
-
Kazoo will cache a copy of the audio stream as a wav file inside of couchdb before you ever hear it.
- In general you "save money" because each IVR message is only purchased once, but used over and over.
Paying ispeech solves the TTS issue.
