The invention provides a vehicle-mounted multimedia speech noise-reduction module. The speech noise-reduction module is characterized in that chips for a hardware part employs an FM FM1388 chip mounted with an external ARM chip and an external memory chip for reading and writing for controlling, so that a firmware algorithm is able to be updated to obtain a daily latest noise reduction algorithm packet at any time. And the FM1388 chip has two groups of ADC analog input interfaces as analog signal inputs or is connected with two analog microphones.
