How to Make the Best AI Caller Speak Your Customer's Language! (VAPI) [2024]

Introduction

In this article, we'll guide you through how to use multiple languages with WPPI and 11 Labs to clone your voice and effectively communicate in different languages. The example provided focuses on German, but the principles apply to any language.

Steps to Implement

1. Choosing the Language and Setting Up Transcription:

   • Begin by preparing the entire system prompt in the target language—in this case, German.
   • Use Deepgram (deep gr) for transcription. Select the appropriate language model, such as de for German.
   • Configure Deepgram to transcribe what it hears in the German language model.

2. Setting Up OpenAI GPT-4:

   • Utilize OpenAI GPT-4 and provide a detailed system prompt in German.
   • Allocate tokens, such as 500, for the conversation flow.
   • Optional: Set up emotion detection to gauge the sentiment.

3. Creating a Voice Clone with 11 Labs:

   • Use 11 Labs to clone the necessary voice. Record sample phrases for cloning, such as, "All our dreams can come true if we have the courage to pursue them."
   • Add the cloned voice model into the system.
   • Configure your settings, such as stability, similarity clarity, exaggeration, and speaker boost.

4. Choosing the 11 Labs Model:

   • Decide between 11 Lab’s Turbo (for lower latency) and Multilingual (for better language depth).
   • Note the latency differences: Turbo has a latency of 1500 ms, while Multilingual can have a latency of 2300 ms.

5. Customizing Additional Features:

   • You can add background sounds, fillers, back channels, and better control over stability settings.
   • Configure features for HIPAA compliance, video recording, and other specific requirements.
   • Set up analysis prompts to determine the success of the call.

6. Testing and Publishing:

   • Once you configure and make changes, you need to publish the changes for them to take effect.
   • Test the configuration by initiating a call and ensuring it speaks in the configured language.

7. Example Interaction:

   • Demonstrated a simulated conversation in German where the AI effectively communicated various prompts and responses.

FAQ

Q: What is WPPI and how is it used in this process? A: WPPI stands for Web Platform Processing Interface. It's used to integrate system prompts and transcription settings to handle multiple languages.

Q: Why should I use Deepgram for transcription? A: Deepgram offers high-quality transcription services and supports multiple language models, making it an ideal choice for transcription needs.

Q: What is the advantage of using OpenAI GPT-4? A: GPT-4 provides advanced natural language understanding and generation capabilities, enabling sophisticated and contextually accurate conversations.

Q: How does 11 Labs help in voice cloning? A: 11 Labs allows you to clone a user’s voice accurately. This is crucial for personalized voice interactions in the selected language.

Q: What are the latency differences between 11 Labs Turbo and Multilingual models? A: The Turbo model has a latency of approximately 1500 ms, whereas the Multilingual model has a higher latency of approximately 2300 ms.

Q: Is emotion detection necessary? A: Emotion detection is optional but beneficial for gauging the sentiment and adjusting responses accordingly.

Q: What precautions should be taken for HIPAA compliance? A: Enable HIPAA compliance settings to ensure no audio recording occurs, thereby protecting sensitive data.

Q: How often should changes be published when modifying the system? A: After every change, the new configuration must be published to take effect immediately.

Q: Can I add background sounds and noise to make the conversation more realistic? A: Yes, background sounds and fillers can be added to enhance the realism of the conversation.

Q: What is the process of testing the final setup? A: Make the necessary configurations, publish changes, and initiate a test call to ensure everything works as expected.
