About SpeedSound AI
SpeedSound is built for churches that want to translate a service live without receivers, interpreter booths or an app. A host opens a room on a phone, picks the spoken language and goes live. Speech is converted to text live and translated while the speaker is still talking, and guests scan a QR code or open a link to read captions in their own language, with newcomers able to join at any point.
The site says guests can pick from more than 20 languages with no login, payment or setup, that listeners are unlimited and that everything runs in the browser from one phone. It contrasts this with traditional setups that need equipment, human translators and one language per channel. Plans are priced by translation time per month, with every supported language included at no extra fee, and the site also lists separate tools for audio to text, voice generation, voice isolation and audio extraction.
