Balabolka Apuohjelma online-puhesynteesipalveluihin

The command line application allows to use online text-to-speech services: text files or subtitles can be converted to audio files. The utility can be used for testing purposes: it will help you to choose a cloud computing service that satisfies your needs. The separate application for Yandex SpeechKit is available for downloading, because Yandex is the Russian IT company with close government ties.

Online services with speech technologies: Google Cloud Text-to-Speech; Amazon Polly; Baidu Text-to-Speech; CereVoice Cloud; IBM Watson Text-to-Speech; Microsoft Azure; Naver Text-to-Speech; Youdao Text-to-Speech; Yandex SpeechKit.
