快速开始
本文为您介绍如何快速调用百炼语音模型服务。
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，请参见获取API Key和配置API Key到环境变量。
已安装SDK。具体操作，请参见安装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。
# 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。
