Hi, I am trying to use a mp3 file in my SSML output.
Using the Alexa Developer Console, I get the following Error:
Error retrieving text to speech
The input was incompatible.
<speak> Hello! <audio src='https://skills.area-i.de/Media/Audio/Applause.mp3'/> </speak>
My seccond approach works fine:
<speak> Hello! <audio src='https://area-i.de/Applause.mp3'/> </speak>
The file is the same in both attempts. The only diffrernce is the host and maybe the certificate.
1st one has a DigiCert Inc SSL certificate
2nd one is signed by Let's Encrypt
Could someone help me with this Problem?
