使用Google-Speech-to-Text,我只能获得部分转录。输入文件:来自谷歌样本音频文件
Link to google repo location commercial_mono.wav
这是我的代码:
def transcribe_gcs(gcs_uri):
from google.cloud import speech_v1p1beta1 as speech
from google.cloud.speech_v1p1beta1 import enums
from google.cloud.speech_v1p1beta1 import types
client = speech.SpeechClient()
audio = types.RecognitionAudio(uri = gcs_uri)
config = speech.types.RecognitionConfig( language_code = 'en-US',enable_speaker_diarization=True, diarization_speaker_count=2)
operation = client.long_running_recognize(config, audio)
print('Waiting for operation to complete...')
response = operation.result(timeout=5000)
result = response.results[-1]
words_info = result.alternatives[0].words
tag=1
speaker=" "
for word_info in words_info:
if word_info.speaker_tag==tag:
speaker=speaker+" "+word_info.word
else:
print("speaker {}: {}".format(tag,speaker))
tag=word_info.speaker_tag
speaker=" "+word_info.word
以下是我调用脚本的方法:
transcribe_gcs('gs://mybucket0000t/commercial_mono.wav')
我只从整个音频文件中获得部分转录
(venv3) ➜ g-transcribe git:(master) ✗ python gtranscribeWithDiarization.py
Waiting for operation to complete...
speaker 1: I'm here
speaker 2: hi I'd like to buy a Chrome Cast and I was wondering whether you
could help me
这就是我得到的全部
如果我多次执行代码,经过5或6次后,我都没有收到任何转录。
以下是几次尝试后的结果:
(venv3) ➜ g-transcribe git:(master) ✗ python gtranscribeWithDiarization.py
Waiting for operation to complete...
speaker 1:
(venv3) ➜ g-transcribe git:(master) ✗
环境:使用python3
当扬声器发生变化时,我试图通过时间戳获得整个转录。
期望的输出
Speaker 1: Start Time 0.0001: Hello transcription starts
Speaker 2: Start Time 0.0009: Here starts with the transcription of the 2nd speaker and so on to the end of file.
希望你能提供帮助。
还没有与v1p1beta有任何问题,但是,在我的最后。
建议#1:可能是一个明显的建议,但你的项目是否允许“数据记录”?这是使用更高级功能/模型所必需的。也许尝试一下?如果没有改变你的结果,你可以在测试后将其关闭。
数据记录参考:https://cloud.google.com/speech-to-text/docs/data-logging
建议#2:尝试使用以下这一行:
client = speech_v1p1beta1.SpeechClient()
建议#3:尝试在配置中添加采样率
sample_rate_hertz = 44100
