icSpeech Professional Edition features a multiple-document interface (MDI) that supports various methods of displaying multiparameter data. These include waveforms, dynamic bar charts, palatograms, video, spectrograms and spectrums. All displays can be synchronously viewed in real-time for visual feedback, recorded for off-line analysis or printed for hard copy. Using cursors, many of the displays allow you to perform precise measurements on the recorded multiparameter data. In addition, the data can be exported to comma-separated values (CSV) files for external processing.

Data recorder

icSpeech Professional Edition can synchronously record multiparameter data. The easy-to-use setup lets you quickly configure the recorder for any combination of instrumentation. The voice prompt feature makes recording fun and interactive. Voice prompts including pictures, words or phrases can be configured to appear during recording and also annotate the recorded data. icSpeech comes complete with a large selection of voice prompts, or you can create your own using the built-in editor. You can also make notes and attach them to the recording.


icSpeech games provide a fun and interactive environment for children to learn about speech. Each of the six games feature adjustable targets, rewards and can be controlled by the multiparameter data, including speech, voice, airflow and lingual. Data from the gaming sessions can also be recorded for off-line analysis.

Pronunciation tools

A set of tools featuring state-of-the-art speech recognition and text to speech technology provide valuable guidance and feedback on pronunciation skills. The tools include Pronunciation Coach, Speech Intelligibility Scorer and Minimal Pairs Tutor.
