Reducing speech service costs

VoiceAI Connect provides mechanisms that reduce the billing costs of third-party, text-to-speech and speech-to-text services. These services charge per consumption, which is a significant part of the cost of the whole voicebot solution. The VoiceAI Connect mechanisms can reduce the cost of speech services by up to 40%.

The first mechanism concerns text-to-speech services, whereby VoiceAI Connect caches the text-to-speech prompts from the bot, eliminating the need to involve the text-to-speech service provider for repeated prompts.

The second mechanism concerns speech-to-text services, whereby VoiceAI Connect utilizes its built-in Digital Signal Processors (DSP) to detect silence and voice from the human participant, and consumes speech-to-text services only when there is voice. In a typical voicebot scenario, the bot and human participant each speak about 50% during the entire conversation. Therefore, this mechanism can be a substantial cost saver. (This mechanism works best with speech providers that don't charge a minimum per speech-to-text request.)
