### Answer You can improve how your agent reads phone numbers by enabling the

normalize_for_speech

setting. [(1) ]() When set to

true

, this will normalize text (including numbers, currency, dates, etc.) to their spoken form for more consistent speech synthesis. For example, it will convert "Call my number 2137112342" to "Call my number two one three seven one one two three four two" before starting audio generation. You can enable this 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
}) ;

Additionally, you might experiment with: - **`voice_speed`**: Controls speech rate (value ranging from 0.5 to 2) . A lower value means slower speech which may help with number cadence. - **`voice_temperature`**: Controls voice stability (value ranging from 0 to 2) . A lower value means more stable/consistent speech generation (applies to 11labs voices) .
