InvTool Software

The InvTool program is used to record speech for the synthesizer.

InvTool Interface

When a person records a database of speech, the InvTool program prompts the person for each word to be recorded. It then processes that speech by, among other things, giving the person feedback on whether the recording was too loud or soft, or too high or low in pitch, and giving the person the choice of rerecording that word or continuing.

InvTool allows users to take a break or stop whenever they wish, and InvTool will automatically start up wherever users stopped during the last session.
