A method of communicating digital speech data to a speech synthesis circuit. The speech synthesis circuit utilizes linear predictive coding techniques for producing high quality speech or other sounds. The digital speech data is preferably stored in a memory which is coupled to the speech synthesis circuit. The data has variable frame lengths. In the disclosed embodiment, four different frame lengths are described having frame lengths from four bits to forty-nine bits. The memory stores the variable frame length data and communicates the same to the speech synthesis circuit in response to certain control signals. The frames for voiced speech include a greater number of bits than for invoiced speech. <IMAGE> |
