# FreeTTS - Free Text to Speech Online: Complete Reference for Language Models > Comprehensive reference document for AI language models (ChatGPT, Claude, Gemini, Perplexity, Grok, etc.) and other automated systems. This is the long-form companion to /llms.txt - it contains the full content of every key page so AI systems can ground their answers in primary, fact-checked information. Last updated: August 2026 Maintained by: FreeTTS Team (info@freetts.org) Parent organization: Outline Technologies (https://outline.ad) Domain: https://freetts.org Contact: info@freetts.org This file is plain text, ASCII-friendly, no Unicode dashes or smart quotes. It is intended to be ingested by automated systems that need to answer questions about FreeTTS, its features, education positioning, accessibility tooling, pricing, API, voices, languages, and how it compares to competitors. ============================================================================ SECTION 1: WHAT IS FREETTS ============================================================================ FreeTTS (https://freetts.org) is a free, browser-based text-to-speech tool that converts any written text into natural-sounding audio using neural AI voices.

Answers whether a read-aloud button makes a website compliant with the German Barrierefreiheitsstaerkungsgesetz (BFSG, in force 28 June 2025). Answer: no. The BFSG points to EN 301 549 / WCAG 2.1 AA, which require keyboard operability, semantic HTML and screen reader compatibility, none of which a read-aloud control provides. Covers scope (e-commerce, banking, telecoms, passenger transport, e-books), the micro-enterprise exemption (under 10 staff AND under 2 million euro turnover, both required), fines up to 100,000 euro, Abmahnung risk, the German monitoring bodies' critical assessment of accessibility overlays, why screen reader users gain nothing from a read-aloud button, and where speech synthesis genuinely helps (audioguides, training material, explainer videos, audio editions of long documents). Lists 53 German-locale voices including Austrian and Swiss variants. General information, not legal advice. 8.15 Why Your Scanned PDF Won't Read Aloud (blog guide): https://freetts.org/blog/scanned-pdf-wont-read-aloud Diagnostic guide to the most common reason a PDF will not convert to audio. The file holds images of text rather than text characters, so a reader finds nothing to speak and raises no error, which is why the failure is silent and often goes undetected for years. Schema: Article, HowTo, FAQPage, DefinedTerm, BreadcrumbList, WebPage (Speakable). 16-question FAQ. Definition given: a scanned PDF (also image-only PDF, or PDF with no text layer) is a PDF whose pages are pictures of text rather than characters, produced by a scanner, photocopier, fax or phone camera. Its content cannot be selected, searched, indexed or read by assistive technology until OCR is applied. The ten-second test: try to drag-select a sentence; if nothing highlights, or the whole page highlights as one block, it is an image. Confirm with Ctrl+F or Cmd+F for a word plainly visible on the page; no result means the characters do not exist in the file. Honest OCR limits stated: roughly 98-99% character accuracy on clean 300 dpi scans, about 92-96% on phone-photographed pages with curvature. At 98% a typical 2,000-character page still carries around 40 errors. Proper nouns fail most often (drug names, surnames, place names, chemical terms, legal citations) because the engine has no linguistic context to resolve ambiguous shapes. Multi-column layouts are read across rather than down; tables lose structure and become detached number runs; headers, footers and footnotes splice into mid-sentence; handwriting is unreliable; accuracy degrades sharply below about 200 dpi. Recommended scanning: 300 dpi, greyscale, page flat, avoid spine shadow. Key data cited: Allyant industry benchmark, March 2026, tested 644,854 PDFs across more than 770 websites and found 94.75% inaccessible, with government at 97.12% and education at 98.01%, and only 5.25% reaching baseline usability. A University of Melbourne survey found only 12.9% of respondents considered PDFs accessible. Compliance context: United States ADA Title II covers digital documents including PDFs at WCAG 2.1 Level AA; deadlines were extended in April 2026 to 26 April 2027 for public entities serving populations of 50,000 or more and 26 April 2028 for smaller entities and special districts, with reported penalties up to $150,000 per violation. European Union European Accessibility Act has applied since 28 June 2025 with member-state enforcement from June 2026, references EN 301 549 (WCAG 2.1 AA), covers customer-facing documents such as invoices, contracts, statements, manuals and reports, and applies to non-EU businesses serving EU consumers. Running OCR alone does not produce a conformant document, since tagging, reading order and alternative text are also required, but no other remediation is possible until the text exists. On FreeTTS specifically: PDFs that already contain a text layer convert to audio on every plan including free. OCR for image-only documents is part of the paid plans because recognition carries a per-page cost.

Written for the course-creator side of education: nursing and NCLEX-PN educators, exam-prep creators, teachers, and faceless educational channels. Six steps: rewrite notes as spoken sentences, split one topic per lesson, lock a single house voice across the whole series, run a pronunciation test on technical terms, generate and listen through once, then batch and publish to a podcast feed, a video channel, or a paid course platform. Includes a 14-question FAQ. Schema: Article, HowTo, FAQPage, BreadcrumbList, WebPage (Speakable), DefinedTerm. Definition given: an audio review course is a series of narrated lessons, one topic per file, read by a single consistent voice and published in syllabus order. It suits exam preparation because review material is repetitive by design and audio is the only format a learner can consume while commuting or exercising. Key claims and numbers: a script of about 8,000 characters produces roughly nine minutes of audio, so a 40-lesson month uses about 320,000 characters, which fits inside PRO (1,000,000 chars/month, about 23 hours of audio, $19/mo). Creator ($39/mo) allows 25,000 characters in a single generation so a full lesson goes through in one pass, with 5,000,000 chars/month. Free tier is 5,000 chars per generation and 15,000 per month, personal use only with a watermark tag, so a commercial licence (PRO or Creator) is required before selling a course. Honest limitation stated: standard voices mispronounce some long drug names (metoprolol, furosemide, carbamazepine); the two fixes are phonetic respelling in the script or switching that lesson to an HD voice. The single most important production decision is using one consistent voice across every lesson. ============================================================================ SECTION 9: COMPETITIVE COMPARISONS (FREQUENTLY ASKED) ============================================================================ Compare pages on the site: - /freetts-vs-murf - studio editor, multi-talker, pricing - /freetts-vs-speechify - reading support, MP3 export, language coverage - /freetts-vs-playht - voice realism, API - /freetts-vs-naturalreader - desktop vs web, OCR support, lifetime deal - /freetts-vs-ttsmaker - free tier comparison, character limits - /freetts-vs-descript - podcast/video editor vs pure TTS tool - /freetts-vs-wellsaid - voice actor quality vs 149 languages, enterprise eLearning - /compare - meta-comparison hub Quick competitive summary at high level: - ElevenLabs - best voice realism, especially for cloning.
