# AI Behavior Issues

> Troubleshoot and optimize your AI assistant's conversation behavior and responses

Your AI's behavior can be fine-tuned through a combination of engine settings and prompt adjustments.

## Engine Settings Impact

Different AI engine modes affect behavior:

### Fast Engine

* Quick, more conversational responses
* May occasionally miss context
* Best for: Simple interactions, sales calls
* Works great with Filler Audio for natural flow

### Standard Engine

* Balanced understanding and speed
* Good for most use cases
* Default recommendation for new assistants

### Accurate Engine

* Deep context understanding
* More thoughtful responses
* Best for: Complex support, detailed information gathering
* May have longer pauses between responses

## Common Issues & Solutions

### Why is the AI Misunderstanding Context?

**Symptoms:**

* AI gives irrelevant responses
* AI doesn't remember information mentioned earlier
* AI asks for information already provided

**Solutions:**

* Switch to **Accurate Engine** for better context understanding
* Add more context to your system prompt
* Include example conversations showing how to handle context
* Use knowledge bases for complex information retrieval

<Info>
  The Accurate Engine processes more context but may have slightly longer response times. This trade-off is worth it for complex conversations.

### How to Fix Unnatural Conversation Flow?

**Symptoms:**

* Awkward pauses between responses
* AI interrupts callers
* Conversation feels robotic

**Solutions:**

* Enable **Filler Audio** for smoother transitions and natural pauses
* Use **Fast Engine** for quicker back-and-forth in sales scenarios
* Add conversation examples in your prompt showing natural dialogue
* Adjust interruption settings to allow natural turn-taking

### Why is the AI Giving Repetitive Responses?

**Symptoms:**

* AI says the same thing multiple times
* Responses lack variety
* AI doesn't adapt to different caller styles

**Solutions:**

* Review and update your system prompt with variation examples
* Add instructions like "vary your phrasing" or "use different words for similar concepts"
* Consider switching to **Standard** or **Accurate** engine for more nuanced responses
* Test with different conversation scenarios to identify patterns

## Optimization Tips

* **Sales Calls**: Fast Engine + Filler Audio for engagement
* **Customer Support**: Accurate Engine for better problem solving
* **Lead Qualification**: Standard Engine for balanced performance

## Testing Changes

After adjusting settings:

1. Use the test call feature
2. Try different conversation scenarios
3. Monitor call recordings for improvement

## Quick Reference: Engine Selection Guide

| Engine       | Speed                    | Context Understanding | Best For                                        |
| ------------ | ------------------------ | --------------------- | ----------------------------------------------- |
| **Fast**     | Very Fast (\~300-600ms)  | Basic                 | Sales calls, quick confirmations, simple Q\&A   |
| **Standard** | Fast (\~800-1200ms)      | Good                  | Most use cases, balanced performance            |
| **Accurate** | Moderate (\~1200-2000ms) | Excellent             | Complex support, detailed information gathering |
