Slovak Text-to-Speech Pronunciation Issues with 'r' and 'l' Since September Update

Roman Ticka 0

Hello,

We are using your Text-to-Speech service in the Slovak language. Since around September, we’ve noticed that certain words containing the letters "r" or "l" are being pronounced incorrectly. For example, the word prvý is pronounced as pvý, skipping the "r". In some cases, we can fix this issue by modifying the phoneme, such as changing pr̩ˈ.viː to prˈ.viː. However, for some words, such as krv, this workaround does not work.

This issue affects all Slovak voices and did not occur before September.

Is it possible to revert to an older version of the service where this issue did not exist? Alternatively, is there a way to resolve this without having to create a dictionary of corrections, as that is not a viable solution for us?

Thank you for your assistance.

Hi Roman Ticka

Welcome to Microsoft Q&A Forum, thank you for posting your query here!

I understand your concerns regarding the pronunciation challenges you’re encountering with the Slovak Text-to-Speech service. The ability to make adjustments directly within the service, creating a custom dictionary of corrections seems to be the primary approach for resolving these issues. This method, while effective in certain cases, can be time-consuming and may not address all the nuances of the Slovak language. I am able to reprove the scenario regarding Slovak Text-to-Speech and able to hear audio correctly. If the issue still persists kindly send me the audio.

kindly refer the below document: https://learn.microsoft.com/en-us/azure/ai-services/speech-service/releasenotes?tabs=speech-sdk#release-notes

Thank You.

Hi @Saideep Anchuri ,thank you for your response and your effort to address this issue. Unfortunately, the problem still persists. See the examples below for reference.

I reviewed the link you provided, but I couldn’t find any mention of changes specifically related to the Slovak language.

Here are examples of the incorrect and correct pronunciations:

Hi Roman Ticka Thank you for sharing the audio examples. I understand the issue is still present despite the workaround. Since there have been no specific updates related to the Slovak language in the release notes, this may be due to an unintended change in the service. As the issue affects all Slovak voices, I recommend submitting feedback directly through the Azure portal, which can help track and address this issue in future updates.Thank You.
