My example returns a nice sounding audio but the lexicon is ignored. Any hints welcome. :)

Region is

My lexicon file:

My lexicon uri:

https://shelf.ir-media-tec.com/azure/tts/lexicon_deDE_ipa.xml

My request JSON:

    "displayName": "sythesis sample",
    "description": "synthesis test",
    "textType": "SSML",
    "inputs": [
        { 
	    "text": "",
        },
    ],
    "properties": {

The lexicon file seems fine and I have validated the same in the TTS lexicon file validation tool.

Have you tried to add the same lexicon file through speech studio and check if lexicon is applied? I have added this lexicon file through speech studio and used it in a file by adding BTW alias and it seems to work. I couldn't validate the original lexeme elements since I am not sure of the pronunciation. I think you could try a similar scenario, add your lexicon from speech studio and then use that in a file in speech studio and then validate if it applies successfully.

If it applies successfully, try to replace the lexicon URI with your external URI and check if the same works. This will ensure that your external URI is not an issue.

Here, you can see from the studio I have used the external URI in SSML view and saved the file. Within the studio you need to update the file at two places as highlighted. But, with batch API you only need to update the file between the <speak> tags for lexicon.
