Description

Text to Speech (TTS) is a text-to-speech extension with natural-sounding voices by using two different TTS engines. The 1st engine is the HTML5 native web speech API for speech synthesis. It is active in all modern browsers by default (more info: https://webaudio.github.io/web-speech-api/). The 2nd API is the Kokoro AI engine, which uses a new artificial intelligence method to synthesize text (more info: https://huggingface.co/onnx-community/Kokoro-82M-v1.0-ONNX). Please note that when you choose Kokoro AI, the app needs to download training data (~300MB) for the AI engine. So please be patient while the app is loading. You can use this extension in a standalone interface or within web pages. If you press the toolbar button, the first interface opens up where you can enter the desired text for TTS. On the other hand, within a webpage, once you select a text, a placeholder speaker icon appears. Once you click the speaker icon, the text-to-speech starts. For the highlight feature to work correctly, please select text paragraph by paragraph. Please note that the highlight feature is still in Beta and may not work properly on all websites. There are also a few options related to the in-page text-to-speech, which can be adjusted from the extension settings page. Note 1: For TTS in webpages, the app only uses the Web Speech API. Kokoro AI engine is only available within the standalone interface. Note 2: Kokoro AI engine, once loaded, can work fully offline. Moreover, you can save the output TTS audio as a .wav file to your machine. When text-to-speech is completed, please press the audio icon on the right toolbar. To report Bugs, please visit the addon's homepage (https://mybrowseraddon.com/text-to-speech.html) and fill out the bug report form.

No sound after pressing the speaker symbol bottom left.Have to paste things in a textbox which is a pain,but could be worthwhile if it actually worked

Breaks page functions providing more burden than help.

Constantly stops and you have to reset the app. Sometimes it'll get 1 sentence in and then stop, other times it will get 3 paragraphs in and then stop.

not enough english voice models, there's this one specific TTS voice model an Epub Reader app called ReadEra has that's just called "en-US-language, Google, United States" and I find it sounds the least headache inducing at 1.75x speed of any TTS voice model I've ever heard, even if it doesn't sound particularly sophisticated

There is no automatic reading, and it doesnt actually read any webpage. Instead, a popup comes up that you have to manually paste all the text into for it to read. It`s a major nuisance, and completely a waste of time (as it takes 2-3x longer just to read anything in this way). Boooooooo. One commentor says 3.4 rating is underrated, I say it`s too high. I wouldn`t recommend this at all.

Not "natural". Only 3 bad voices available.

Most of voices stops speech after 50 words. Some voices say "dot". No speech speed.

This interferes with changing the text styles in Gmail in th Edge browser. When I'm typing a Gmail reply and highlight some text to change it to italic or bold or anything, the highlight becomes un-highlighted and no style change happens. Had to remove it to solve the problem.

Cuts off very soon. US voices are bad, use UK instead (and live with the accent). Too many "joke voices" like "bubbles" (one would be too many but 8 out of 10 are like this... useless I mean...). Thanks for the effort but I will not be using this.

Can't adjust the speed, the reading speed is too slow

Like many say it is slow and should have a speed control but it is fine for me since I can't read fast anyways but I would like to change the voice and also the highlighting text function failed soon after it began.

Cuts off, and also very slow. Would love some alternate speeds.

This is an easy to use extension, but it won't switch to others languages on my computer. It only uses french voice.
