Description

The audio2text service is almost the same as the asr service, except for the returned data object type. We should combine both of them to minimize maintenance effort

Hi @lianhao due to a legacy issue huggingface/tokenizers#187, the first implementation of these ASR/TTS code is to split the microservice start and the model initialization to different places. Basically it is because our microservice are initialized in the other process using register_microservice and the huggingface tokenizer just fail with that case.

It is a bit annoying before I finally get some solutions to avoid such situations. I fully agree we should combine these two services together and remove the wrapper, same to tts service. I am starting to look into this together with the OpenAI format compatible feature.
