### Answer Enable the

normalize_for_speech

setting on your agent. [(1) ]() [(2) ]() [(3) ]() When set to

true

, this will normalize numbers, currency, dates, and similar text to their spoken form for more consistent speech synthesis. For example, 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"

You can enable this via the API when creating or updating your agent:

javascript
const agentResponse = await client.agent.create({
  response_engine: { llm_id: 'llm_234sdertfsdsfsdf', type: 'retell-llm' },
  voice_id: '11labs-Adrian',
  normalize_for_speech: true
}) ;

[(1) ]() Or when updating an existing agent:

javascript
const agentResponse = await client.agent.update('16b980523634a6dc504898cda492e939', {
  normalize_for_speech: true
}) ;

[(3) ]() You can also enable this setting in the Dashboard under your agent's configuration. [(1) ]() [(3) ]()
