How2Say sγur Willian Carlos da Silva

How2Say is a Firefox extension to help you to know how to pronounce a word showing its IPA and playing its audio.
Formerly How2Pronounce, but I lost the access to the account.

• Select a word or text
• Right click to open the context menu and click the extension item
• Or, in Firefox Android, click the extension menu, then the addon icon
• ✨ Magic ✨

Features

• Show word IPA
• Play audio pronunciation
• Allow to provide custom IPA and audio through the options page
• Works for texts
• Allow enable/disable IPA/audio for words and/or texts
• Allow control audio with a player for texts (enable/disable through options)
• Allow control audio with shortcuts for texts (enable/disable through options)
• Highly customizable through the options page

Configuration

The addon experience can be customized through the options page.
IPA and audios source order can be configured dragging the sources to change the priority, and enable/disable them.
By now, the addon supports these API's, which all of them offer a free limit per month, only requiring to sign their site to get the key/token and provide in the options page, which will be stored only in your device. They are:
- ResponsiveVoice (the only with a key by default)
- Unreal Speech
- Speechify
- PlayHT
- ElevenLabs
- AmazonPolly (1 year of free tier)
- OpenAI (there is no free tier)

Tip: if you have a good internet speed, decrease the Real voice fetch timeout (ms) to around 1200.

For developers

The files in ./src/bundle/*.js were generated with npx rollup --config --bundleConfigAsCjs rollup.config.js due module usage.
It was used fflate to decompress the gzip IPA file in the installation. The script was downloaded from here https://cdn.jsdelivr.net/npm/fflate@0.8.2/umd/index.js and is in ./src/utils/fflate.js.
It was used SortedJS in the options page. The script was downloaded from here https://cdnjs.cloudflare.com/ajax/libs/Sortable/1.15.6/Sortable.min.js and is in ./src/utils/Sortable.min.js.
