SpeechGen

SpeechGen provides online AI voice generation using neural synthesis to produce natural-sounding speech from text. It offers thousands of voices and languages and emphasizes browser-based use without requiring software installation. The tool is designed for creators, educators, marketers, and teams that need scalable, multilingual voiceovers and audio content.

SpeechGen operates by offering a library of voices and language options, with a focus on quick previews, customizable parameters, and a straightforward workflow. Users type or paste text, select a voice and language, and generate audio in formats like MP3, WAV, or FLAC. The service supports SSML and various audio settings to tailor output.

The main features include a large voices library (5,000+ voices), 150 languages, a pay-as-you-go model with credits, built-in tools for editing and segmentation, and an API for developers. Outputs can be used for voiceovers, podcasts, e-learning content, IVR prompts, and localization workflows. The platform also provides caches to speed up re-generations and tracking across projects.

SpeechGen outlines plans to scale via credit packs and emphasizes cross-platform use in a browser, with access to 30-day history and a 1-year credit validity on top-ups. It highlights that credits can be spent across voice tiers and transcription, and that formats supported include MP3, WAV, and OGG, with integration options via API.
