ASR对热词的支持

[823639792]

我尝试修改 \services\websocket_asr.py中
asr_engine.offline_model.generate 与
asr_engine.realtime_model.generate
以增加支持热词，但是怎么都不生效

            result = await run_sync(
                asr_engine.realtime_model.generate,
                input=audio_array,
                cache=cache,
                is_final=is_final,
                chunk_size=chunk_size,
                encoder_chunk_look_back=encoder_chunk_look_back,
                decoder_chunk_look_back=decoder_chunk_look_back,
                hotword="xxx  20"
            )
