如何在不保存到文件的情况下听IBM Watson文本到语音结果(python)

如果对外部库开放，可以使用pip install python-vlc安装用于python的vlc绑定 并使用播放器方法播放音频直接从以下内容。

import vlc
from ibm_watson import TextToSpeechV1
from ibm_cloud_sdk_core.authenticators import IAMAuthenticator

authenticator = IAMAuthenticator('{apikey}')
text_to_speech = TextToSpeechV1(
    authenticator=authenticator
)

text_to_speech.set_service_url('{url}')


#define VLC instance
instance = vlc.Instance('--input-repeat=-1', '--fullscreen')

#Define VLC player
player=instance.media_player_new()

#Define VLC media
media=instance.media_new(
text_to_speech.synthesize(
            'Hello world',
            voice='en-US_AllisonVoice',
            accept='audio/wav').get_result().content)

#Set player media
player.set_media(media)

#Play the media
player.play()

vlc播放器的优点是你可以直接从URL播放大多数媒体类型(不仅仅是mp3)，也可以执行类似播放器的选项，比如

>>> play.pause()  #pause play back
>>> player.play() #resume play back
>>> player.stop() #stop play back
