Text-to-Speech and Speech Recognition Technology
So Natural and Accurate, It Could Be Human



Speech Technology Group offers powerful 64-bit text-to-speech and speech recognition technology. Our value proposition is to provide exceptional quality at an affordable license model with a passion for reliable and responsive support.


TrueVoice TTS After vast improvements to the voice synthesizer, the quality of our Text-to-Speech engine is now far superior to the mechanical voices still installed on many automated systems. Our voices are very natural and have a high degree of syntactical accuracy (correct pronounciation of proper names). They can be deployed in cloud, server, desktop, embedded and mobile environments and come with a broad variety of standard interface options.

Try the automatic TTS converter to the right and hear it for yourself.

TrueVoice ASR technology can be deployed in server and cloud-based environments using the industry standard MRCP interface. The 64-bit speech engine is very efficient (up to 96 channels per server), highly accurate and supports large grammars and 26 languages.

Thousands of companies from SMB to Fortune 1000 are using these powerful ASR and TTS engines, which are integrated with leading platforms like Asterisk, Avaya and Genesys. Cisco has officially certified the 64-bit speech engine with CVP and their MRCP enabled routers.

The license model is very affordable and allows the technology to be deployed even in very budget sensitive projects without compromising quality.
