Hello @Luciana Rodrigues Domingues Britis , Thanks for using Microsoft Q&A Platform.
I have reproduced using the speech-to-text feature in Speech Studio, and as indicated in the screenshot below, personal information has been transcribed as well.
The issue may not be related to the speech service. Please check the PA parameters once more.
I hope this helps.
Regards,
Vasavi
