Pyttsx3 Cross Platform Tts Generator

The ‘pyttsx3’ library is a cross-platform Text to Speech generator, offering language-specific voice options, adjustable speech rate, and file saving capabilities for playback. It utilizes default engines on Windows and macOS, and requires espeak for Linux.

By looking into the NaturalLanguage Framework on macOS, I find text classifier and embeddings inside.

It will leverage default TTS engine on Windows and macOS, but for linux you must install espeak.

import pyttsx3
engine = pyttsx3.init()
# dir(engine.getProperty("voices")[0]) -> ['age', 'gender', 'id', 'languages', 'name']
# The voices are related to languages. Set it properly.
# you want "en_US" and "zh_CN"
# [['en_US'], ['it_IT'], ['sv_SE'], ['fr_CA'], ['de_DE'], ['he_IL'], ['id_ID'], ['en_GB'], ['es_AR'], ['nl_BE'], ['en-scotland'], ['en_US'], ['ro_RO'], ['pt_PT'], ['es_ES'], ['es_MX'], ['th_TH'], ['en_AU'], ['ja_JP'], ['sk_SK'], ['hi_IN'], ['it_IT'], ['pt_BR'], ['ar_SA'], ['hu_HU'], ['zh_TW'], ['el_GR'], ['ru_RU'], ['en_IE'], ['es_ES'], ['nb_NO'], ['es_MX'], ['en_IN'], ['en_US'], ['da_DK'], ['fi_FI'], ['zh_HK'], ['en_ZA'], ['fr_FR'], ['zh_CN'], ['en_IN'], ['en_US'], ['nl_NL'], ['tr_TR'], ['ko_KR'], ['ru_RU'], ['pl_PL'], ['cs_CZ']]
engine.setProperty('voice', engine.getProperty("voices")[39].id)
engine.save_to_file("你好 世界", 'output.wav')
engine.runAndWait()
engine.setProperty('rate', 125) # setting up new voice rate
# The punctuals make the bot to pause for some time. Maybe you should control that yourself.
engine.save_to_file("你好，世界", 'output.wav')
engine.runAndWait()
