No direct.

For example, a low rate vocoder “codec2” was applied to the RLSpeakTM solution, which coding rates are 700b/s, 1300b/s and 2400b/s. The coding rate here is refer to the rate of coding and compressing the PCM data stream generated after the analog voice input and converted by A/D codec.

The vocoder rate in the voice communication line (for example, the transmission rate of the GSM network full-rate FR mode is 13Kb/s) is used to compress the voice secondly, which is compressed, encrypted and modulated, according to the vocoder standard of corresponding communication lines.

There is no direct relationship between the above two, please do not confuse.
