Acapela Group vs TTSReader

Acapela Group creates synthetic voices that turn written content into speech for services, apps, and devices. Its portfolio includes more than 250 voices in over 30 languages, with voice cloning, API access, and commercial use supported. Customer interaction products can be deployed through cloud, sovereign cloud, on-premises, or embedded setups. Acapela Cloud provides a web interface for creating and editing AI voice prompts and organizing files by project. Developers can use the Windows Server toolkit with proprietary APIs, SAPI5,.NET, C/C++, Java, MRCP v2, and W3C SSML. Rule-based pronunciation and lexicon tools allow specific terms to be tuned across languages. Acapela identifies voice agents and interactive voice response systems as use cases, and its NVDA voices serve blind and vision-impaired computer users. Platforms include Android, API, iOS, Linux, macOS, self-hosted, web, and Windows. The yearly subscription is €99 a year, billed excluding VAT; a three-month voice evaluation is included. Acapela is based in Mons, Belgium.

TTSReader converts text and documents into speech, reads webpages aloud, and can create downloadable audio. It supports PDF, DOCX, TXT, CSV, and EPUB files, with MP3 and WAV listed as export formats and a maximum input of 200000. Voices come from Google, OpenAI, xAI, Microsoft, and proprietary AI providers. During playback, the reader highlights the current text and remembers the article and position so listening can resume later. Users can edit text while it plays and combine voices, languages, and speeds in one file. The service identifies proofreading, education, accessibility, language learning, audiobook creation, and voice-over production as uses. Its website plugin is free and includes playback controls, voice and speed selection, automatic scrolling, and saved preferences; the maker says it does not track users, use cookies, or show ads. API access is available, though the synchronous API recommends only a few thousand characters, calls 5k safe, and notes requests can time out after five minutes. The Free plan costs nothing and is for personal use only, with 5k premium-voice characters. Premium is $10.99 a month for one user and 1,000,000 premium characters per month. Pay-as-you-go plans cost $10 a month for 200,000 characters, $32 a month for 1,000,000, or $300 a month for 10,000,000; credits expire after one year, extended by each new purchase.
