You can ask Alexa to pronounce a word given its spelling. Works with all English words. In case Alexa misheard you or suspects that you provided an incorrect spelling, she will still pronounce the word and then will give you some suggestions on what the correct spelling could be.
This skill works well if you enunciate the letters clearly and slowly.
When used on an Android or iOS device, the skill can also help you learn more about the word by launching the Merriam-Webster™ app or webpage at the end of the session.
The skill is designed for both voice-only Alexa devices and Alexa devices with a screen.
