# Voice & Personality

> Choose how your AI sounds and communicates. Pick a voice, set the tone, and make it yours.

Your AI should sound like it belongs to your business. Choose a voice, set the communication style, and make it feel like a natural extension of your team.

***

## Choosing a voice

LumisReach offers multiple AI voices. Each has different characteristics:

### Voice options

| Voice            | Description                        | Best for                             |
| ---------------- | ---------------------------------- | ------------------------------------ |
| **Professional** | Clear, confident, business-like    | Law firms, financial services, B2B   |
| **Friendly**     | Warm, approachable, conversational | Home services, healthcare, retail    |
| **Energetic**    | Upbeat, enthusiastic, dynamic      | Sales, fitness, youth-oriented       |
| **Calm**         | Soothing, patient, reassuring      | Healthcare, therapy, senior services |

### Previewing voices

Before choosing, preview each voice with sample phrases:

1. Go to Settings → Voice
2. Click "Preview" on each option
3. Hear how it sounds with your business name
4. Select the one that fits

***

## Voice speed and tone

Beyond the voice itself, adjust how it speaks:

### Speaking pace

| Setting    | Effect                                |
| ---------- | ------------------------------------- |
| **Slower** | More deliberate, easier to understand |
| **Normal** | Natural conversational pace           |
| **Faster** | More energetic, efficient             |

<Tip>
  Slower pace works well for technical explanations or older audiences. Faster pace suits energetic brands and younger demographics.
</Tip>

### Tone adjustments

Fine-tune the emotional quality:

* **Warmth**: How personable and caring
* **Formality**: How professional vs. casual
* **Energy**: How enthusiastic vs. measured

***

## Communication style

### Greeting

How does AI answer the phone?

**Formal:**

> "Good afternoon, thank you for calling Johnson Law Firm. How may I assist you today?"

**Friendly:**

> "Hi there! Thanks for calling Johnson Plumbing. What can I help you with?"

**Efficient:**

> "Johnson HVAC, how can I help you?"

Customize your greeting in Settings → Scripts → Greeting.

## Personality traits

Give your AI personality guidelines:

### Examples

**For a law firm:**

* Be professional and authoritative
* Use precise language
* Never make promises about case outcomes
* Express empathy for difficult situations

**For a plumbing company:**

* Be friendly and down-to-earth
* Use simple, clear language
* Express urgency for emergency calls

**For a medical practice:**

* Be warm and compassionate
* Use calm, reassuring tone
* Be patient with questions
* Never give medical advice

### Setting traits

Go to Settings → Personality and add traits like:

* "Be friendly but professional"
* "Use the customer's name when possible"
* "If someone seems frustrated, be extra patient"
* "Always end with 'Is there anything else I can help with?'"

***

## What AI calls itself

### Introduction

How does AI introduce itself?

**As an AI:**

> "Hi, this is the AI assistant for Johnson Plumbing. How can I help?"

**As a team member:**

> "Hi, thanks for calling Johnson Plumbing. How can I help you today?"

<Note>
  When directly asked if they're speaking to a human, AI will always be honest. It won't pretend to be human.
</Note>

### Name

Give your AI a name if you want:

* "This is Alex from Johnson Plumbing"
* "This is the scheduling assistant for Johnson Plumbing"
* No name: "Thanks for calling Johnson Plumbing"

***

## Outbound prompt

When your AI makes outbound calls (campaigns, workflows, follow-ups), it uses a separate greeting and set of instructions from your inbound configuration.

### Configuring outbound defaults

1. Go to your phone number's **Voice** tab.
2. Expand the **Outbound Prompt** section.
3. Set your **Outbound Greeting**, the first thing the AI says when calling someone.
4. Set your **Outbound Instructions**, the way the AI should behave during outbound calls.

<Tip>
  Outbound calls have different dynamics than inbound. The person didn't initiate the call, so your greeting should identify who's calling and confirm it's a good time to talk.
</Tip>

### Example outbound greeting

> "Hi there! This is an AI assistant calling on behalf of Johnson Plumbing. Is now a good time to talk?"

### Example outbound instructions

* State the purpose of the call clearly and concisely.
* If they're busy, offer to call back at a better time.
* If they're not interested, be gracious and end the call.
* If you don't have the answer, offer to find out and follow up.

<Note>
  Individual campaigns and workflows can override these defaults with their own scripts. The outbound prompt serves as the fallback when no specific script is provided.
</Note>

## Testing your settings

After configuring voice and personality:

1. **Call your number** and have a conversation
2. **Listen to how it sounds.** Does it match your brand?
3. **Try different scenarios.** Friendly caller, frustrated caller, quick question
4. **Review transcripts.** Does the text read the way you want?
5. **Adjust and repeat.** Fine-tune until it feels right
