SpeechGen

SpeechGen.io is a browser-based text-to-speech tool that converts written text into spoken audio. Users paste in text, choose from more than 5,000 neural voices spanning over 150 languages, and download the result as MP3, WAV, FLAC, or other audio formats. The platform supports SSML markup for controlling pauses, pitch, emphasis, and intonation, and can assign different voices to different paragraphs to create multi-voice dialogues. It also includes a subtitle-to-audio sync feature and can process PDF and DOCX documents, with generation limits up to two million characters at once. SpeechGen is built for people who need voiceovers without hiring voice talent: marketers, e-learning course creators, businesses building phone or IVR systems, museums producing audio guides, localization teams, and podcasters. A built-in background music library and a smart cache that lets identical text be regenerated for free are aimed at reducing the cost of iterating on a script. Pricing is pay-as-you-go rather than subscription-based: a free tier offers 1,000 characters with no signup, and 3,000 characters per day for a week after registration, with paid tiers priced by voice quality starting at $4.99. A REST API is available for programmatic use, and the platform connects to automation tools like Zapier, Make, and n8n. The company's founding year is not stated on the site.
