TaskSpeech Lab

TaskSpeech® Lab (TSL) is a standalone speech & voice laboratory. With this analysis app, you can explore automatic speech recognition (ASR) under various controlled conditions. TSL provides both educational and speech-research value in a small-footprint package, and is for designers, programmers, researchers, teachers and learners. It gives you direct hands-on experience, promoting a deeper understanding of ASR's inner workings. The resulting knowledge informs the design, development and testing of any speech and voice applications you may be considering. - Comes with default vocabulary and settings -- just download, tap and speak. - You can create your own vocabulary and settings easily. - Everything is driven by a parameter (text) file: you edit or create new parameter files to run your experiments. - No need to be connected to the internet, everything runs locally on the iPhone. - Learn about grammars and language models, end-pointing, nBest and error types. - Sample files and example vocabularies available free online. - Uses free, speaker-independent, open source, connected speech from CMU PocketSphinx project. - Useful for personal experimentation, classroom and lab instruction, workshop presentations and more.
