DMR voice vocoder

The DMR voice vocoder is a digital vocoder used in digital mobile radio (DMR) systems to compress and decompress voice signals. The vocoder is responsible for encoding and decoding the user's voice signal into a digital format that can be transmitted over the DMR network.

The DMR voice vocoder uses a technique called digital speech interpolation (DSI) to compress voice signals. DSI works by analyzing the user's voice signal and transmitting only the portions of the signal that contain actual speech. This allows for more efficient use of bandwidth and reduces the amount of data that needs to be transmitted.

When the compressed voice signal is received by a DMR radio, the vocoder then decodes the signal and reconstructs the user's voice signal. The decoded signal is then sent to the radio's speaker or headset for playback.

Overall, the DMR voice vocoder plays a critical role in enabling clear and efficient communication over DMR networks.
