Bug Report

Installation Method

Docker / windows

Environment

v0.3.35
TTS via matatonic/openedai-speech

Win 10 / FF latest

Confirmation:

  • [ x] I have read and followed all the instructions provided in the README.md.
  • [x ] I am on the latest version of both Open WebUI and Ollama.
  • I have included the browser console logs.
  • I have included the Docker container logs.
  • [x ] I have provided the exact steps to reproduce the bug in the "Steps to Reproduce" section below.

Expected Behavior:

All visible alphanumeric "text" that makes up the visible markdown should be sent to the TTS service during TTS "Read Aloud" playback.

Actual Behavior:

Some text, like italicized text is not being played back during TTS "Read Aloud" playback.

Description

Bug Summary:
I noticed during Read Aloud playback that some words were skipped. I noticed a pattern that its almost always italicized markdown text not being played back. It can be other markdown text, though. Sometimes it reads invisible hash tags.

Reproduction Details

Steps to Reproduce:
(see attached sample of json and wav output)

  1. Configure a working TTS server so you can properly use the "Read Aloud" feature.
  2. Start a chat and edit the response to the example markdown provided below.
  3. Press "Read Aloud"
  4. Listen
  5. Notice it skipped some words entirely... sometimes

 # Sample Markdown Paragraph

Markdown is a lightweight markup language that you can use to format text. It is often used to style *documents*, **web pages**, and even readme files. For example, you can create:

- A bulleted list
- **Bold text**
- *Italic text*
- `Inline code`

To emphasize certain words, you can use _italic_ or __bold__ formatting, or both together like this: **_Bold and Italic_**. If you want to create a block of code, you can wrap it in triple backticks:

Adding here that..... I don't know the correct answer about some text being sent to TTS.

For example, the TTS service is reading the # hashtag symbol that is presented to it in the json.
However, because its not visualized to the reader since its just a header markdown symbol, it likely shouldn't be sent to the TTS service.

But, if I write "Hey Carl, this is a hashtag #", open-webui needs to send that hashtag to be read by TTS.
