NaturalReader
Reads web pages, Google Docs, PDFs, emails and Kindle books aloud in natural-sounding voices so you can listen instead of reading.
Chrome extension
Converts typed or selected text into lifelike synthetic speech in the browser and lets you save the audio as an MP3 file.
AIVocal converts typed or selected text into synthetic speech in Chrome and lets you save the result as an MP3. It suits people who want articles, documents and emails read aloud, and creators who need voice audio for their projects.
Select text on a page or type it into the extension, choose a voice and play or download the audio.
Text is sent to AIVocal's service to generate the audio. Syncing a voice library across devices implies using an account with the service.
