Thank you for reaching out to Microsoft Q&A forum!
The issue you're encountering with the whispering style in SSML might stem from differences in how the Azure Voice Generator tool and the Azure TTS API handle SSML tags. The API might not fully support applying the
<mstts:express-as style="whispering">tag to individual words within a sentence, even though it works in the Voice Generator tool.To work around the issue, try applying the whispering style to larger chunks of text rather than just individual words. For instance, group the word you want to emphasize with its surrounding context into a larger segment and apply the style to that entire segment. This approach ensures that the style is applied consistently across the text.
I hope you understand. Do let us know if you have any further queries.

Thank you for the response and pardon me for the late reply, kindly can you please share any documentation or rules related to such scenarios like what are the cases in which the speech services (TTS) allow the use of single or pair of words for
<mstts:express-as style=[style]>SSML tag. I tried different scenarios which sometimes randomly worked and sometimes didn't both individually and for many words.
Please let me know if anything in detail is required or to discuss more, looking forward to your reply.Thanks -

2024-09-24T12:55:08.72+00:00 Hi @IJazulhassan,
Thank you for your follow up query.
For Azure Text-to-Speech (TTS) using SSML, specific guidelines and limitations exist regarding how certain SSML tags, like mstts:express-as style="whispering", can be applied. The behaviour can vary depending on the tag's application to individual words or larger segments.
You can refer to SSML overview for Azure Speech Services, which covers best practices, supported tags, and limitations.
Typically, SSML tags like mstts:express-as are designed to be applied to entire phrases or sentences rather than single words. Applying the tag to single words might not consistently work due to how the TTS engine processes the voice style, which may explain why your usage has been unpredictable. The general recommendation is to apply these tags to larger segments to ensure consistent results.
I hope you understand. Thank you.

Thank you for the assistance but still I didn't get any clear rules regarding the mentioned tag as sometimes it behaves differently even in the group of words despite when I add some marks i.e. "!" within it or something like that, then it works (occasionally).
Kindly assist with it (with ref to the proper documentation).
Thanks. -

2024-10-23T10:59:07.1766667+00:00 Hi @IJazulhassan,
Thank you for your follow-up. The behaviour of certain SSML tags can be inconsistent, especially when applied to shorter text segments or when punctuation like exclamation marks is involved. For more detailed guidelines on how these tags are processed, you can refer to SSML overview, which outlines supported tags and best practices.
Since the behaviour can vary based on punctuation or specific word groupings, experimenting with different phrase structures or reducing punctuation might help. If this doesn't resolve the issue, contacting Azure support may provide more insights into handling these edge cases.Thank you.
