如何快速调用灵积语音模型服务_智能语音交互(ISI)-阿里云帮助中心

本文为您介绍如何快速调用灵积语音模型服务。

说明

若您有合作需求或技术咨询，请提交工单。

前提条件

已开通服务并获得API-KEY。具体操作，请参见开通DashScope并创建API-KEY。
已安装SDK。具体操作，请参见安装DashScope SDK。

示例代码

以下示例展示了调用Paraformer语音识别文件转写API，对一个通过URL给出的音频文件进行语音识别的代码。

说明

需要使用您的API-KEY替换示例中的your-dashscope-api-key，代码才能正常运行。
通过URL指定进行语音转写的文件，其大小不超过2GB。
file_urls参数支持传入多个文件URL，示例中仅展示对一个文件URL进行转写。

Python

# For prerequisites running the following sample, visit https://help.aliyun.com/document_detail/611472.html

import dashscope
from urllib import request
import json

dashscope.api_key='your-dashscope-api-key'

task_response=dashscope.audio.asr.Transcription.async_call(
    model='paraformer-v1',
    file_urls=['https://dashscope.oss-cn-beijing.aliyuncs.com/samples/audio/paraformer/hello_world.wav']
    )

transcription_response=dashscope.audio.asr.Transcription.wait(task=task_response.output.task_id)

transcription_url=transcription_response.output['results'][0]['transcription_url']
transcription_results=json.loads(request.urlopen(transcription_url).read().decode('utf8'))
print(json.dumps(transcription_results, indent=4, ensure_ascii=False))

调用成功后，将会返回例如以下示例的文件转写结果。
