Windows機でテキストを読み上げさせる(3.5回目)

3回目で使ったwinsdkは廃止されるので、代替のモジュールを使う。
必要なモジュールをインストールする: 
pip install winrt-Windows.System winrt-Windows.Storage winrt-Windows.Storage.Streams winrt-Windows.Foundation winrt-Windows.Media winrt-Windows.Media.Core winrt-Windows.Media.Playback winrt-Windows.Media.SpeechSynthesis
そして、実行する: 
import asyncio
from winrt.windows.media.core import MediaSource, MediaSourceState
from winrt.windows.media.playback import MediaPlayer
from winrt.windows.media.speechsynthesis import SpeechSynthesizer

# 確認用
# for voice in SpeechSynthesizer.get_all_voices(): print('{} / {} / {} / {} / {}'.format(voice.id, voice.display_name, voice.language, voice.description, voice.gender))
# print(SpeechSynthesizer.get_default_voice())

async def synthesize_text(text, voice=None):
	synth = SpeechSynthesizer()
	if voice is not None: synth.voice = voice
	return await synth.synthesize_text_to_stream_async(text)

async def play(stream):
	player = MediaPlayer()
	player.source = MediaSource.create_from_stream(stream, stream.content_type)
	player.play()
	while player.current_state != MediaSourceState.CLOSED: await asyncio.sleep(.5)

stream = asyncio.run(synthesize_text('13番線に停車中の列車は、17時30分発、寝台特急、北斗星1号、札幌行きです'))
print(stream, stream.size, stream.content_type)
asyncio.run(play(stream))
print('done')
