Settings
The Settings tab controls how your voice agent sounds and behaves. Settings are organized into sections: Voice Settings, Call Settings, Post-Call Analysis, and Widget Settings.
Voice Settings
Language
Set the primary language for the agent's greeting using the language dropdown.
| Aspect | Description |
|---|---|
| Initial language | The agent greets callers in this language |
| Auto-switching | The agent automatically switches to the caller's language |
| Multi-language | The agent understands and responds in multiple languages |
The language setting primarily affects the greeting. Once the conversation begins, the agent adapts to whatever language the caller uses.
STT Languages
Use the multi-select field to specify up to 4 languages for speech-to-text recognition (e.g., en, de, ru, or the longer en-US, de-DE forms). This improves recognition accuracy for multilingual environments — for example, a German business that also serves English and Turkish speakers.
When set, only these languages are used for speech recognition. Leaving the field empty means the agent auto-detects based on the primary language.
Both short language codes (en, de) and region-specific codes (en-US, de-DE) work. The platform automatically picks a sensible regional variant when you give it a short code.
Voice Selection
Click the Voice field to open a selection modal where you can browse and preview available voices. Voices differ by gender, tone, accent, and speaking style.
Voice Fine-Tuning
| Setting | Description | Range | Default |
|---|---|---|---|
| Volume | Adjust how loud the agent speaks (in dB) | -90 to +100 | 0 |
| Speed | Adjust how fast the agent speaks | -20 to +30 | 0 |
Choosing the Right Voice
| Business Type | Recommended Voice Style |
|---|---|
| Professional services | Calm, mature voice |
| Youth brands | Energetic, younger voice |
| Healthcare | Warm, reassuring voice |
| Tech support | Clear, patient voice |
| Sales | Confident, enthusiastic voice |
Preview voices before selecting — click on a voice name to hear a sample. Match the voice to your brand personality.
Background Ambience
(v2.8) Give the call a subtle sense of place by playing a background sound behind the agent's voice. Choose from a small set of ambiences, set how loud it should be, and preview it instantly before you commit.
| Ambience | Feels like |
|---|---|
| Office | A busy workplace behind the agent |
| Coffee shop | Relaxed café atmosphere |
| Call center | A staffed support desk |
| Outdoors | Open-air, outside |
| Rain | Calm, rainy background |
| Reception | A front-desk / lobby feel |
| Setting | Description | Default |
|---|---|---|
| Ambience | Which background sound to play (or none) | Off |
| Volume | How loud the ambience sits under the voice | — |
Background Ambience is off by default. Use the instant preview to check the mix — the ambience should stay well under the agent's voice so it never competes with what the caller needs to hear.
A light ambience can make an agent feel more human and less "recorded". Keep the volume low — a background that draws attention away from the conversation does more harm than good.
Region-Aware Localization
(v2.2) When you deploy an agent to a specific region — de-AT, de-CH, en-GB, and so on — the platform automatically applies that market's conventions at the start of the call. You don't configure anything; picking the region does the work.
This affects how the agent:
- Reads numbers and currency in the local convention
- Speaks banking codes (IBAN, sort codes, etc.) the way that market expects
- Formats addresses to the local standard
- Uses the region's TTS conventions so the voice sounds native rather than a generic variant of the language
The result: an de-AT agent sounds Austrian, an en-GB agent sounds British, without you tuning the prompt for each market.
Call Settings
End Call After Silence
A toggle that controls how the agent handles caller silence. When turned on, the call ends automatically after a period of silence. Use the slider to set the silence duration.
| Setting | Description | Range | Default |
|---|---|---|---|
| Toggle | Enable or disable silence-based call ending | On / Off | Off |
| Timeout | Seconds of silence before ending the call | 10–30 seconds | 10s |
When silence mode is on, the Reminder settings below are disabled — the two modes are mutually exclusive.
Reminder System
When silence mode is off, the agent uses reminders to re-engage silent callers instead of ending the call.
| Setting | Description | Range | Default |
|---|---|---|---|
| Reminder Trigger | Seconds of silence before sending a reminder | 10–30 seconds | 30s |
| Reminder Max Count | How many reminders before ending the call | 1–10 | 3 |
The reminder system works as follows:
- Caller goes silent
- After Reminder Trigger seconds, the agent sends a reminder (e.g., "Are you still there?")
- If still silent, repeats up to Reminder Max Count times
- After all reminders, the agent ends the call politely
Either use End Call After Silence or Reminders — they are mutually exclusive. Silence detection ends the call immediately; reminders give the caller more chances to respond.
Interruption Sensitivity
Control how readily the agent stops talking when the caller starts to speak. This is a per-agent setting that sits alongside the silence and reminder controls.
| Setting | Description |
|---|---|
| Interruption sensitivity | How eagerly the agent yields the floor when the caller speaks over it |
- Higher sensitivity — the agent stops almost immediately at the first sound from the caller. Good for fast, back-and-forth conversations, but background noise can cut the agent off mid-sentence.
- Lower sensitivity — the agent needs a clearer, more sustained interruption before it stops. Good for noisy environments or agents that read out longer passages, but the caller has to be more deliberate to break in.
If callers complain the agent talks over them, raise the sensitivity. If the agent keeps getting cut off by background noise, lower it.
Max Call Duration
Set a hard ceiling on call length. When the cap is reached, the agent politely ends the call no matter what's happening in the conversation. Useful for cost control on outbound campaigns, demo-call scenarios, and any setup where you want a guaranteed upper bound on talk time.
| Setting | Description | Range | Default |
|---|---|---|---|
| Toggle | Enable or disable the duration cap | On / Off | Off |
| Duration | Maximum call length in minutes | 1–15 | 10 (when first enabled) |
The cap applies to every entry point for this agent — incoming phone calls, outbound dials, browser test calls, and callback widget calls. It does not affect calls handled by other agents.
When the cap fires, the agent ends the call within a couple of seconds. The call appears in the call log, flagged as ended by the duration limit.
Leave the cap off for normal customer-support and receptionist agents — natural call length serves the conversation. Turn the cap on for outbound campaigns where unbounded calls inflate your costs, for demo agents you embed in landing pages, or for any agent talking to anonymous visitors.
The Callback Widget has its own safety ceiling of 10 minutes per call. If you also set a Max Call Duration on the agent, the shorter of the two wins.
Customer Memory
Toggle to let the agent remember previous conversations with the same caller.
| Setting | Description | Default |
|---|---|---|
| Customer Memory | Toggle on/off — when enabled, the agent retains context from past calls with the same contact | Off |
When enabled:
- The agent recognizes returning callers and references previous conversations
- Context from past calls is available to the AI during the conversation
- Creates a more personalized experience for repeat callers
Example: A returning customer calls about their order. The agent says: "Welcome back! Last time we spoke about your delivery to Vienna. How can I help today?"
Recording Enabled
Toggle call recording on or off. When enabled, all calls handled by this agent are recorded.
| Setting | Description | Default |
|---|---|---|
| Recording Enabled | Toggle on/off — when enabled, all calls are recorded | Off |
When enabled:
- Full audio recordings are saved with each call log
- Access recordings from the Call Logs section
- Useful for quality assurance, training, and compliance
Check local laws regarding call recording consent. Many jurisdictions require you to inform callers that they are being recorded. Consider adding a notice in your agent's first message.
Post-Call Analysis
Automatically analyze calls after they end.
Sentiment Analysis
Toggle to track the caller's emotional tone throughout the conversation.
| Sentiment | Description |
|---|---|
| Positive | Caller is satisfied, happy, or appreciative |
| Neutral | Normal conversation tone |
| Negative | Caller is frustrated, unhappy, or angry |
Enable this to:
- Monitor customer satisfaction trends
- Identify problematic call patterns
- Improve agent prompts based on sentiment data
- View sentiment in call logs
Call Summary
Toggle to automatically generate a summary of each call with key phrases and topics discussed.
When enabled, after each call you get:
- A concise summary of the conversation
- Key phrases and topics identified
- Action items mentioned during the call
View summaries in the Call Logs section.
Quality & Testing Aids
Two built-in aids help you keep an agent on track — they live with the prompt on the Model tab rather than in Settings:
- Prompt Tester — simulate a conversation with the agent right in the dashboard, then get concrete suggestions for improving the prompt based on how the simulated call went. Use it to catch gaps before real callers hit them.
- Guardrails — monitor the agent for drift, flagging when its behaviour strays from what the prompt intends.
See Prompt Engineering for how to use these while iterating on your prompt.
Widget Settings
The agent's Widgets tab is the home for everything widget-related: the theme picker, the callback widget configuration with its own language picker, the embed snippets for the in-browser widget types, and the domain restrictions that apply to all widgets.
| Setting | Description | Default | Limits |
|---|---|---|---|
| Theme | Color theme used by all widgets | "tangerine" | 11 themes available |
| Callback widget | Enable the phone-callback widget, configure retry attempts, retry interval, and widget language | Disabled | See Callback Widget |
| Terms & Conditions | Show a consent dialog before the conversation starts | Disabled | Content max 5,000 chars |
| Allow all domains | Allow widget to be embedded on any website | true | — |
| Allowed domains | If "Allow all" is off, the list of domains permitted to embed | [] | Max 50 domains |
See Website Widgets for the in-browser widget types and embed snippets, and the dedicated Callback Widget page for the phone-callback widget.
