以下是一个使用AWS Polly和AWS Transcribe服务来实现通过语音收集字母输入的示例代码:
import boto3
def convert_text_to_speech(text):
polly_client = boto3.client('polly')
response = polly_client.synthesize_speech(
Text=text,
OutputFormat='mp3',
VoiceId='Joanna'
)
# 保存语音文件
with open('speech.mp3', 'wb') as file:
file.write(response['AudioStream'].read())
import boto3
def convert_speech_to_text(audio_file):
transcribe_client = boto3.client('transcribe')
response = transcribe_client.start_transcription_job(
TranscriptionJobName='SpeechToText',
LanguageCode='en-US',
MediaFormat='mp3',
Media={
'MediaFileUri': 's3://bucket-name/' + audio_file
}
)
# 获取转换后的文本
while True:
job = transcribe_client.get_transcription_job(TranscriptionJobName='SpeechToText')
if job['TranscriptionJob']['TranscriptionJobStatus'] in ['COMPLETED', 'FAILED']:
break
if job['TranscriptionJob']['TranscriptionJobStatus'] == 'COMPLETED':
response = boto3.client('s3').get_object(Bucket='bucket-name', Key=job['TranscriptionJob']['Transcript']['TranscriptFileUri'])
text = response['Body'].read().decode()
print(text)
def call_flow():
# 获取用户输入的字母
text = input("请输入字母:")
# 将字母转换为语音
convert_text_to_speech(text)
# 将语音转换为文本
convert_speech_to_text('speech.mp3')
请注意,上述示例仅提供了基本的框架,您可能需要根据实际需求进行修改和扩展。另外,您需要在AWS控制台上配置适当的访问密钥和权限,以便使用AWS Polly和AWS Transcribe服务。
