System and method for correcting errors when generating a TTS voice

A tangible computer-readable storage medium storing instructions for controlling a computing device to enable human workers to find errors when developing a text-to-speech (TTS) voice, the instructions comprising:

• presenting a graphical user interface wherein after a first pass of automatic speech recognition (ASR) of a speech corpus is complete, the interface presents to a worker a graphical representation of an alignment of the ASR results, associated words and phonemes and the audio;
• color-coding each word based on a composition of the color-coding associated with each phoneme;
• receiving a graphical input from the worker associated with a selection of a word or phoneme;
• and
• presenting the audio associated with the selected word or phoneme.
