Speech control system and control method of automobile seat

Abstract

The invention provides a speech control system of an automobile seat. The speech control system of the automobile seat has high speech recognition accuracy and diversified functions. The system comprises a speech entering unit arranged in the host machine of an acoustic system; the speech entering unit enters the speech of a passenger and driving noises, processes entered speech signals and transmits the processed speech signals to a sound processing unit; the sound processing unit comprises a noise reduction module, a digital-to-analog signal conversion module and a speech recognition control module; the speech signals which have been subjected to the noise reduction of the noise reduction module are transmitted to the digital-to-analog signal conversion module; the digital-to-analog signal conversion module converts speech analog signals into speech digital signals and synchronously sends the speech digital signals to the speech recognition control module; and the speech recognition control module transmits a result to a seat execution unit through a CAN bus-bar. According to the speech control system of the automobile seat of the invention adopted, a speech recognition unit and the sound processing unit in the host machine of the acoustic system are utilized, and therefore, speech recognition is clear and accurate; instructions are transmitted through the CAN bus-bar; and therefore, the intelligent and diversified control of the seat can be realized.

Description

Technical field [0001] The invention relates to the application field of automobile electronics, in particular to a voice control system for a car seat and a control method thereof. Background technique [0002] Vehicle voice recognition is a new technology that has just developed in recent years.

Problems solved by technology

Among them, the voice module is integrated in the voice thermostat. This patent has a single function and only supports voice control of the seat temperature. At the same time, because the voice module is built into the seat, the input of the voice is not clear, which affects the overall effect of voice recognition control.
