## Customize the Persona for Your Agent in Agentforce Builder

Customize your agent’s voice by modifying the voice settings. While the voice settings can be updated at any stage, we recommend adding a voice-enabled connection such as Telephony to your agent first. The voice settings apply to all voice-enabled connections for that agent. To modify the voice settings, first make sure that your agent is deactivated.

1. From the App Launcher, enter Agent, and then select the **Agentforce Studio** app. On the Agents tab, click the name of your agent.
2. In the Explorer panel, under Agent Definition Settings, select **Voice Settings**. These voice settings apply to all voice-enabled connections that you add to this agent.
    
    ![Explorer panel with voice settings highlighted](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-ai-generative_ai-264-0-0-production-enus/f8ef6498-d7b2-44e3-9b34-ffd5a850aae9/generative_ai/images/agent_explorer_voice_settings.png)
3. Select a persona from the drop down menu and review its description. Enter a message in the Preview Message field and click **Play** to test the audio.
4. Use the Advanced section to further fine-tune the persona. Make sure to test the settings and consider your audience and content and adjust the settings if necessary.
    - Speed: Allows you to either speed up or slow down the pace of the generated speech.
    - Similarity: Controls how closely the generated speech matches the original persona you selected.
    - Stability: Determines how stable the voice is and the randomness between each generation. Lower values allow for more expressiveness and higher values make speech less expressive or more monotone.
5. Under the Pronunciation Dictionary, add any words or phrases that are unique to your organization or use case and are likely to be mispronounced. This is an optional step. Review the [Agentforce Voice Best Practices guide](https://help.salesforce.com/s/articleView?id=ai.agentforce_voice_best_practices.htm&release=264.0.0&type=5 "Voice-enabled agents require distinct conversational design patterns compared to text-based agents to handle spoken interaction effectively.") for more details.
    
    - Word: Add the word or phrase.
    - Pronunciation: Specify the pronunciation for the word or phrase you entered.
    - Type: Select the type of pronunciation dictionary to use: Select CMU for English and IPA for non-english speech. The Carnegie Mellon University (CMU) dictionary is an American English pronunciation dictionary using a simplified ASCII-based phoneme set (ARPA) for speech technology (e.g., "cat" is K AE T). The International Phonetic Alphabet (IPA) is a global system using unique characters, often from Latin and Greek, to represent speech sounds (e.g., "cat" is /kæt/). Tip Listen to the agent pronouncing the word or phrase in the voice preview to determine if the word or phrase required adding it to the pronunciation dictionary.
    
    ![Basic and Advanced settings sections of the voice settings page](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-ai-generative_ai-264-0-0-production-enus/f8ef6498-d7b2-44e3-9b34-ffd5a850aae9/generative_ai/images/voice_settings_combined.png)
6. Under the Keyword Boosting, enter single terms or phrases that are unique to your organization or might be difficult to translate to text. Keyword boosting can improve the ability of the model to correctly recognize terms and phrases you specify. While the pronunciation dictionary provides the phonetic spellings or pronunciation guidance, keyword boosting helps the model recognize the terms and phrases and transcribe more accurately.
    
    - Enter single terms or phrases such as uncommon words, proper nouns, product names, and industry-specific terms.
    - Capitalize keywords as you want them to appear in transcripts.
    - Limit to 100 keywords.

    Note This is an optional step it should only be used if words or terms are being misinterpreted or transcribed incorrectly and after careful testing.
