### Answer Beyond the pronunciation dictionary, here are some approaches to improve name pronunciation: 1. Enable

normalize_for_speech

[(1) ]() [(2) ]() Setting this to

true

will normalize text (numbers, dates, currency, etc.) to spoken form for more consistent speech synthesis. [(1) ]() 2. Use Boosted Keywords [(1) ]() [(2) ]() Add names to the

boosted_keywords

array to bias the transcriber model so those words are more likely to be transcribed correctly. This is commonly used for names, brands, and street names. [(1) ]()

json
"boosted_keywords": ["retell", "kroger"]

3. Prompt Engineering with Spelling Guidelines [(3) ]() You can add instructions in your prompt to guide how the agent should spell out or pronounce specific content. For example, for emails:

///## How to spell out
The possible email format is name@company.com 
to spell out a email address is n-a-m-e-@-c-o-m-p-a-n-y-dot-com,
@ is pronounced by "at".

4. Select an Appropriate Voice Model [(1) ]() [(2) ]() Different voice models may handle pronunciation differently. You can experiment with available options like

eleven_turbo_v2

,

eleven_multilingual_v2

,

sonic-2

, etc. [(1) ]() 5. Adjust Voice Temperature [(1) ]() [(2) ]() The

voice_temperature

setting (range [0,2]) controls voice stability. Lower values mean more stable pronunciation, while higher values introduce more variation. [(1) ]() For more details, check out the [Prompt guide & examples for specific situations]() . [(3) ]()
