Apparatus and method for inspecting speech recognition

This invention describes a way to test how well speech recognition systems work. It does this by taking a written sentence, turning it into a spoken sound using specific voice characteristics and speaking styles, and then feeding that sound to the speech recognition system. Finally, it compares the system's output text to the original written sentence to measure its accuracy. The claims specifically detail using separate parameters for speech features (like speed or tone) and speaker features (like voice identity) to create the spoken sound.

Why it matters: Filed before the explosion of advanced AI speech synthesis. The ability to generate highly realistic and diverse spoken utterances with precise control over speech and speaker characteristics has dramatically improved, making the core testing method far more effective and easier to implement.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
