About TTSLark

TTSLark is an online text to speech service for people who publish audio and video: short-form creators, narrators, course makers and language learners. Paste a script, pick a voice or blend two, then download an MP3 with SRT and VTT subtitles timed to the same render.

What every plan gives you

• One credit makes up to 10 minutes of audio. That is enough for a full YouTube video, a story chapter or a course lesson. The free plan gives you five credits every month.
• Commercial use on every plan. Audio from the free plan can go on a monetized channel, a client project or a paid course. There is no watermark, no spoken ad and no attribution line.
• Make a voice of your own. Blend any two of our 54 voices, choose which one sets the pronunciation and set the mix from 10 to 90 percent. That is more than 23,000 combinations, across languages too, so you can build a one-of-a-kind voice and save it under your own name.
• Subtitles from the render, not from a guess. The SRT and VTT files come from the same synthesis pass as the audio, so cue boundaries land on real pauses.
• No character limit. Paste a whole chapter or episode. The service splits it at sentence boundaries, renders the pieces and joins them into one continuous file.
• 54 voices in nine languages. English in American and British accents, Mandarin Chinese, Japanese, Spanish, French, Italian, Portuguese and Hindi. Every voice has three preview clips you can play free before you spend a credit.

How it is built

Standard voices run on speech models that TTSLark hosts itself, so free renders do not depend on a metered third-party API. Rendering runs on our servers with a progress bar for every job, and long jobs keep going after you close the tab. Your first render gets priority, and paid plans get priority on every render. Audio and subtitle files are stored privately and delivered through signed download links, as the privacy policy describes in detail.

Who runs it

TTSLark is built and run by the TTS Lark Dev Team, a small independent team. The same team reads every support message. Pricing is simple: a free plan with five credits a month and two subscriptions that add priority rendering, WAV output and an AI tidy pass. The tidy pass adds breathing pauses to long lines and spells out symbols and units. It also marks the intended reading of Chinese characters that have more than one pronunciation. There is no enterprise tier and no sales call. Voices are named after characters, not after real people.
