Over 100 million devices with Alexa have been sold worldwide. This service will allow your listeners to play your station through their Alexa smart device by saying "Alexa, play your station name". You can also add your own custom (Alexa synthesised) intro and outro if desired.
If your station is listed on well known apps, such as TuneIn, then your listeners may already be able to find your station on Alexa. However there are still a number of advantages to having your own Alexa Skill. Firstly, if your station has the same or a similar name as another station then it can end up sending your listeners to a completely different station! Having your own Skill reduces the risk of this happening, it also increases your exposure on Amazon as your Skill will have its own page on the Amazon website. Finally, having your own Skill allows you to have a customised voice intro and outro if desired.
