My voice agent keeps pronouncing the brand name AGA as “XRGX” and sometimes “X”. I don’t know why even though it has explicit instructions to pronounce it “Argah” or “ah-gah” in a pronunciation section. I have also given it clear insructions in “speech settings”.

Can anybody help?

Based on the available sources, the pronunciation dictionary feature in Retell AI only works with English agents using 11Labs voices that have selected the `eleven turbo v2` (English only) voice model.[(1)](https://docs.retellai.com/build/add-pronunciation)

To use the pronunciation dictionary, you need to set it for the agent with the word to be pronounced, the phonetic alphabet to use (`ipa` or `cmu` are supported), and the phonetic pronunciation of the word.[(1)](https://docs.retellai.com/build/add-pronunciation)

You can configure this through the API when creating or updating an agent using the `pronunciation_dictionary` parameter:[(2)](https://docs.retellai.com/api-references/update-agent)[(3)](https://docs.retellai.com/api-references/create-agent)

```json
"pronunciation_dictionary": [
  {
    "word": "AGA",
    "alphabet": "ipa",
    "phoneme": "ɑːɡɑː"
  }
]

```

[(2)](https://docs.retellai.com/api-references/update-agent)[(3)](https://docs.retellai.com/api-references/create-agent)

For finding the correct phonetic pronunciation, you can use tools like the IPA pronouncing dictionary tool at [https://tophonetics.com/](https://tophonetics.com/) or the CMU pronouncing dictionary tool at [The CMU Pronouncing Dictionary](http://www.speech.cs.cmu.edu/cgi-bin/cmudict/.%5B(1)%5D(https://docs.retellai.com/build/add-pronunciation))

If you’re experiencing inconsistent pronunciation even after setting up the pronunciation dictionary correctly, this could be a technical issue. Based on community discussions, some users have reported that pronunciation settings don’t always apply consistently, and it may require troubleshooting the specific formatting or checking if there’s a sync issue.[(4)](https://discord.com/channels/1186424376300679209/1186462578310910112/1458931419744043129)

Make sure you’re using:

- An English agent[(1)](https://docs.retellai.com/build/add-pronunciation)
- An 11Labs voice[(1)](https://docs.retellai.com/build/add-pronunciation)
- The `eleven turbo v2` voice model[(1)](https://docs.retellai.com/build/add-pronunciation)
