你好,我在进行一个功能实现,使用ESP-ADF框架,具体功能是需要检测到声音时进行录音采集,静音时不进行处理,当前使用到了VAD检测,主要实现方法如下:
...... #define VAD_SAMPLE_RATE_HZ 16000 #define VAD_FRAME_LENGTH_MS 30 #define VAD_BUFFER_LENGTH (VAD_FRAME_LENGTH_MS * VAD_SAMPLE_RATE_HZ / 1000) ...... vad_inst = vad_create(VAD_MODE_4); //级别过滤 int sample_buffer_size = VAD_BUFFER_LENGTH * sizeof(short); //960 byte int16_t *vad_buff = (int16_t *)audio_malloc(sample_buffer_size); while (1) { raw_stream_read(raw_read, (char *)vad_buff, sample_buffer_size); vad_state_t vad_state = vad_process(vad_inst, vad_buff, VAD_SAMPLE_RATE_HZ, VAD_FRAME_LENGTH_MS); if (vad_state == VAD_SPEECH) { if (http_state_value) { i2s_stream_set_clk(i2s_stream_reader, VAD_SAMPLE_RATE_HZ, 16, 1); // 修改录音采样率16000与VAD保持一致 audio_pipeline_stop(http_pipeline); audio_pipeline_wait_for_stop(http_pipeline); audio_pipeline_reset_ringbuffer(http_pipeline); audio_pipeline_reset_elements(http_pipeline); audio_pipeline_terminate(http_pipeline); audio_element_set_uri(http_stream_writer, "http://xxxxx"); audio_pipeline_run(http_pipeline); http_state_value = 0; } } }
实测下来服务器接收到的录音在播放的时候语速会变的非常快,日志没有报出错误,录音数据也正常上传,但是采集到的录音语速很快,请问这样问题解决方向应该从哪方便入手?

@meibao-real 这个问题可能有两种原因,一是传数据的时候不及时,被迫丢了些数据,这个听起来会变快,声音不完整;二是采样率配置不正常,可能采集是16k,而播放是32k。你可以先将录音数据存储到sdacrd中,来看是哪种原因。
Sorry, something went wrong.
