While telisma delivers high quality general purpose acoustic libraries, teliSpeech TTK allows you, with specific application data, to get the best recognition rates for specific tasks. The TTK helps to tune the acoustic library and application grammars.
The TTK - AE, is a separate product intended for companies which have significant amounts of speech data at their disposal. This TTK AE allows large-scale tuning and optimisation of acoustic libraries. With it, you can effectively create your own version of an existing teliSpeech language, optimised for a specific regional accent, application, or acoustic environment, e.g. particular noise conditions.
