Zero Footprint Prompts
Nowspeak TTS technology is designed to speak dynamic data, such as caller ID and phone names. However, because our TTS voice quality is so good it is possible to use it to speak fixed device prompts, offering 100% reduction in the memory required for compressed prompts.
This offers developers a viable, zero footprint alternative to compressed pre-recorded prompts when flash space is at a premium.
Include NowSpeak TTS as part of your Bluetooth voice interface and you get fixed prompts for no additional memory cost.
