In azure TTS speech playground, there is no way to generate speech

I'm in the speech playground text to speech area. It feels like there should be a box to enter text but there isn't. There is however, a "try it out" in each voice sample. However, entering text in that area and clicking play produces no sound. The only sound I can get is to click on the play button on each actor to hear a sample sentence.

Any idea why?

In the Foundry Speech playground, the Voice gallery view is only for browsing and previewing built‑in sample sentences for each voice. That view doesn’t expose the main free‑text input box, which is why only the per‑voice sample playback works.

To enter custom text and generate speech, switch to the dedicated text‑entry experience instead of staying in Voice gallery:

  1. In Microsoft Foundry, open the Speech playground.
  2. Go to Text to speech.
  3. Use one of these options:
    • In Foundry (new): select Azure Speech – Text to Speech from Build → Models to open the Text to Speech playground where a text box is available and the Play button reads whatever text is entered.
    • In Foundry (classic): in the Speech playground, select Text to speech, then use the Try it out tab, which includes a text box and Play button for custom text.

If only the sample clips play and custom text still produces no audio, verify system audio output (device not muted, correct output device selected) and try another browser or machine to rule out local audio issues.

    Thanks. Based on your quickstart link I finally found the right page. After clicking build, there is no "model" to click on. I clicked around and found the model page. Then I searched the models and found the azure text to speech page. Hope I can find it next time.azure tts

    Hello @Peter

    Thank you for reaching out to Microsoft Q&A.

    From your description, you are using the **Speech Playground → Text to Speech experience in **Microsoft Foundry, and while you can preview voice samples from the Voice Gallery, the system does not generate audio from your custom text.

    Expected behavior clarification

    In the current Speech Playground experience:

    • The Voice Gallery is designed to preview pre-recorded sample sentences for each voice.
    • The “Try it out” section is intended for custom text-to-speech synthesis.
    • Normally, entering text and clicking play should generate synthetic audio output.

    Based on your description, the behavior you are seeing (no audio output when using “Try it out”) is typically caused by one of the following:

    1. Playground UI context not fully initialized

    In some cases, the Speech Playground session may not properly load the required workspace/project context. When this happens:

    • The UI appears functional
    • Text input is accepted
    • But the synthesis request does not execute, resulting in no audio output

    2. Workflow mismatch in the UI

    Some versions of the Speech Playground require selecting a specific Text-to-Speech generation workflow (not just the Voice Gallery view). If this workflow is not active:

    • The system only supports voice preview
    • Custom text synthesis may not trigger correctly

    3. Browser/session-related issue

    This can also occur due to:

    • Cached session tokens
    • Browser restrictions (cookies, tracking prevention)
    • Network/proxy policies blocking the synthesis request

    Recommended troubleshooting steps

    Please try the following:

    1. Refresh the Speech Playground page and reselect a voice
    2. Ensure you are in the Text-to-Speech generation mode not only Voice Gallery preview
    3. Try using a different browser (Edge or Chrome recommended)
    4. Open the page in an Incognito/Private window
    5. Check if the “Try it out” panel appears with active synthesis controls after reload
