### Answer To ensure numbers, currency, square footage, and other terms are pronounced correctly, you should enable the

normalize_for_speech

setting on your voice agent. [(1) ]() When set to

true

, this will normalize text (numbers, currency, dates, etc.) to their spoken form for more consistent speech synthesis. Example from the documentation: > It will convert "Call my number 2137112342 on Jul 5th, 2024 for the $24.12 payment" to "Call my number two one three seven one one two three four two on july fifth, twenty twenty four for the twenty four dollars twelve cents payment" before starting audio generation. You can set this when creating or updating your agent:

javascript
normalize_for_speech: true

Additionally, for domain-specific terms like "sqft" or brand names, you can use: 1.

boosted_keywords

– Bias the transcriber to recognize specific terms more accurately

javascript
   boosted_keywords: ["sqft", "retell", "kroger"]

2.

pronunciation_dictionary

– Define exact pronunciations using IPA phonemes (currently supported for English & 11labs voices)

javascript
   pronunciation_dictionary: [
     {
       "word": "actually",
       "alphabet": "ipa",
       "phoneme": "ˈæktʃuəli"
     }
   ]
