SpeechGen.io
SpeechGen.io is an online text-to-speech platform that turns written text into downloadable voiceovers. The editor supports 5,000+ voices across 150 languages and regional accents, with controls for speed, pitch, volume, and SSML markup for pauses, emphasis, and intonation.
Beyond basic TTS, SpeechGen.io includes voice cloning from short audio samples, subtitle-to-speech conversion for SRT, SUB, and VTT files, and audio-to-text transcription for uploaded files, YouTube links, and video. Export options include MP3, WAV, OGG, FLAC, and other formats at multiple bitrates.
Credits are pay-as-you-go with no subscription. New accounts receive free credits to test the service, and purchased credits stay valid for up to one year. A Smart Cache feature reuses previously generated sentences at no extra cost when you edit and re-export projects.
