Visit Tool →
SpeechGen Brief overview
SpeechGen.io is a browser-based AI text-to-speech (TTS) tool that turns written text into natural-sounding voice audio. It focuses on quick voiceover creation with a large voice library and broad language coverage, making it useful for creators, marketers, educators, and teams producing narration for videos, ads, courses, podcasts, and presentations.
In addition to text-to-speech, SpeechGen also includes audio-to-text (transcription) tools, which can be helpful if you need to convert audio or video content into text, subtitles, or timestamped transcripts.
Simple how-to-use
- Open SpeechGen.io in your browser.
- Choose the language that matches your text.
- Pick a voice from the available voice list (you can usually preview voices before generating).
- Add your content by pasting text into the editor or uploading a supported file (such as DOCX or PDF). If you’re working with subtitles, use the subtitles-to-audio option.
- Adjust settings (optional): change speed and pitch, add pauses, use SSML controls, and (if needed) build multi-speaker dialogue.
- Click Generate Speech, preview the result, then download the audio in your preferred format.
