Description:
American English male speaker for festival, 16khz sample rate
This is a diphone database for festival that uses 16k samples for high quality sound output. This is a large database (9 MB), and festival will convert text to speech more slowly using it, so you might want to install festvox-kdlpc8k instead if you have low disk space or a slow computer. . The voice contained in this database is an American English male speaker. A different American English voice can be found in the festvox-kallpc16k package if you dislike this one.
