A new 1.2 kbit/s speech coding method based on a sinusoidal harmonic vocoder A New 1.2 kbit/s Speech Coding Method Based on a Sinusoidal Harmonic Vocoder Minoru Kohata Chiba Institute of Technology, Narashino, Japan 275-0016 SUMMARY A very low bit rate speech coder at 1.2 kbit/s is proposed in which a speech signal is synthesized by using sinusoids whose frequencies are multiples of the fundamen- tal frequency, and whose amplitudes are adaptively modu- lated in accordance with auditor
