Abstract

The invention discloses a method and device for processing information, relates to the technical field of voice, and can be used for an automatic driving or voice interaction scene. According to one specific implementation scheme, the method comprises the following steps: acquiring an audio signal acquired by vehicle-mounted audio acquisition equipment; generating a time division multiplexing signal according to the acquired audio signal and a corresponding reference audio signal; storing the generated time division multiplexing signal into a preset data cache pool; and sending the time division multiplexing signal in the data cache pool to a preset vehicle-mounted terminal application so that the vehicle-mounted terminal application performs preset processing on the time division multiplexing signal acquired from the data cache pool. According to the embodiment, the time division multiplexing signal is generated according to the audio signal and the corresponding reference audio signal, and the time division multiplexing signal is sent to the vehicle-mounted terminal for application, so that the integrity and real-time performance of the reference audio signal relative to the audio signal acquired by the vehicle-mounted audio acquisition equipment are ensured, and the acoustic echo cancellation effect is improved.

Description

technical field [0001] The embodiments of the present disclosure relate to the field of computer technology, and in particular to the field of voice technology. Background technique [0002] With the rapid development of artificial intelligence technology, voice interaction has been widely used in vehicle systems, greatly improving the experience of human-computer interaction. During the driving process of the vehicle, there will be sounds such as the airflow noise of the vehicle running, the engine noise, and the broadcast sound from the vehicle speaker. This makes the audio quality collected by the audio collection equipment in the car poor, which greatly affects the accuracy of speech recognition. In practice, a factor that greatly affects audio quality is acoustic echo, which refers to the echo caused by the sound broadcast by the speaker being picked up by the microphone. If you want to cancel the acoustic echo, you need to obtain the echo reference signal. The integ...
