TTSFree

TTSFree works entirely in the browser: you type or paste up to the character limit of your plan, choose a language and voice, optionally tweak speed, pitch and pause settings, and generate an audio file. The free guest tier handles 500 characters per conversion and roughly 50 conversions a day, while a registered free account raises the single-conversion limit to 2,000 characters with 500,000 characters per month. Paid plans lift the ceiling to 10,000 characters per conversion (Basic, $5/month) or 40,000 characters (Premium, $20/month).

The voice catalogue spans standard AI voices on the free and Basic plans and premium neural models on Premium, described by the site as including Wavenet, Neural2 and natural human-like voices. Paid plans also add SSML support, background-music integration, no-ads experience and priority support. The Premium tier bundles 5,000,000 API characters per month for teams that want to generate speech from their own scripts and pipelines. Extra character packs can be purchased separately with a 30-day validity window.

The service states that generated audio can be used commercially without attribution and that users keep the intellectual rights to their output, including audio produced during a subscription that has since lapsed. Text and audio are described as processed securely rather than stored. Pricing is billed in US dollars, listed as a one-time plan purchase rather than a recurring subscription, with a 7-day money-back guarantee.
