Chirvo: offline Text to speech

Turn your PDFs, EPUB ebooks, Word documents and notes into listening with Chirvo. Choose a natural-sounding voice, follow the text or keep listening with your screen off. Speech is generated on your device, so you can listen offline once the required voice files are ready without uploading your documents to a cloud speech service.
READ PDFS ALOUD
Listen to reports, research papers, study notes and other PDFs you already have. Chirvo’s PDF text to speech lets you switch between reading and listening, search for a passage and save bookmarks. Follow along with text highlighting where supported.
BRING YOUR OWN BOOKS AND DOCUMENTS
• Import PDF, EPUB, DOCX, TXT and Markdown files.
• Hear EPUB ebooks and Word documents read aloud.
• Write or paste a note and turn it into speech.
• Keep your reading material in a searchable library.
• Resume reading and listening from your saved position.
LISTEN YOUR WAY
Choose natural-sounding English and multilingual voices for supported languages.
• Adjust playback speed to suit your pace.
• Continue listening in the background or with your screen off.
• Set a sleep timer for your listening session.
• Read along on screen or listen hands-free.
SCAN TEXT AND LISTEN
Take a photo of a printed page or choose an image to extract supported Latin-script text with on-device OCR. Review and edit the recognized words before saving and listening.
Recognition depends on image quality and page layout. Check important text for errors.
TRANSLATE WITH CHIRVO PRO
Save a translated copy of an imported document while keeping the original. Read the translated text or listen in a supported voice language.
Translation runs on your device, powered by Google Translate, after the required language models are downloaded. Translation and voice language availability may differ. Automatic translations can contain errors.

PRIVATE, ON-DEVICE PROCESSING
Document text extraction, speech generation, OCR and supported translation run on your device. Your documents and generated speech are not uploaded to a Chirvo server.
Offline listening is available when the required voice files are ready. Internet access may be needed for voice or translation model downloads, purchases and limited SDK diagnostics. See our Privacy Policy for details.
A chapter on a walk, a report on your commute or notes between study sessions, Chirvo helps you keep up with your own reading material when looking at the screen isn’t convenient. Import a file, choose a voice and make time to listen.
