| Abstract: | A digital speech record and play system based on ADSP-2181 DSP chip and ITU-TG.723.1 code and decode standard is introduced, and the implementation scheme is offered. Operation principle of every function module is introduced. As the core module of the system, ADSP-2181 DSP chip cooperates with other function modules to attain digital speech record and play purpose. The principle of the ITU-TG.723.1 standard arithmetic is also introduced. This system can be used in any system to meet the digital speech record and play requirement. |
