在Ruby中使用Amazon转录流式转录

require 'aws-sdk-transcribeservice'

# 创建TranscribeClient对象
transcribe_client = Aws::TranscribeService::Client.new(region: 'us-west-2')

# 定义转录任务参数
job_name = "my-transcription-job"
language_code = "en-US"
media_format = "mp3"
media_file_uri = "s3://my-bucket/my-audio-file.mp3"

# 创建转录任务
transcribe_client.start_transcription_job({
  transcription_job_name: job_name,
  language_code: language_code,
  media_format: media_format,
  media: { media_file_uri: media_file_uri }
})

# 获取转录任务状态
resp = transcribe_client.get_transcription_job({ transcription_job_name: job_name })
status = resp.transcription_job.transcription_job_status

# 等待转录任务完成
while status == "IN_PROGRESS"
  sleep(5)
  resp = transcribe_client.get_transcription_job({ transcription_job_name: job_name })
  status = resp.transcription_job.transcription_job_status
end

# 获取转录结果
if status == "COMPLETED"
  transcription_result_uri = resp.transcription_job.transcript.transcript_file_uri
  # 可以通过下载转录结果文件或者直接读取转录结果内容
  # 下载转录结果文件
  transcribe_client.get_object({ bucket: "my-bucket", key: URI.parse(transcription_result_uri).path[1..-1], response_target: "transcription_result.json" })
  # 读取转录结果内容
  transcription_result = transcribe_client.get_object({ bucket: "my-bucket", key: URI.parse(transcription_result_uri).path[1..-1] }).body.read
  puts transcription_result
else
  puts "Transcription job failed: #{resp.transcription_job.failure_reason}"
end
