TLDR
A high quality Speech synthesizer system which consists of 3 LSI chips, a speech synthesizer, a 128k bit ROM and a general purpose microprocessor has been developed, based on the recently developed PARCOR voice compression technique.Abstract:
A high quality speech synthesizer system which consists of 3 LSI chips, a speech synthesizer, a 128k bit ROM and a general purpose microprocessor has been developed. This system is based on the recently developed Partial Autocorrelation (PARCOR) voice compression technique. This system can generate high quality speech from a data rate of less than 2400 bits per second. Several new techniques are applied for this system to improve the quality of generated speech especially of the female voice. This system has many advantageous features such as speech speed control and external pitch excitation.read more
