Getting great results often comes down to picking the right engine settings. Use this checklist when configuring a Famulor assistant.

​
1. Pick a Mode

Want to know more about the differences? See the Assistant Modes guide.
Record the same scenario in both modes and compare response time and caller satisfaction.

​
2. Choose a Transcriber (Pipeline only)

Different languages, accents, and background noise can affect each engine differently. Run a quick A/B test and keep the best performer.

​
3. Select an LLM Model

If speed is critical, start with Gemini 2.5-Flash-Lite. For sophisticated reasoning, use GPT-4o and offset latency by shortening replies.

​
4. Noise Cancellation

If callers are on speaker phone or in a quiet environment, keep noise cancellation ON. If your call volume is low or some words are “clipped,” turn it OFF so the transcriber gets the full waveform.
If the assistant isn’t hearing you well, try turning noise cancellation off.

​
5. Conversation Timers

Test different values in real calls—too low can interrupt, too high leaves awkward gaps.

​
6. Initial Message

​
7. Ambient sound

Ambient sound adds subtle background noise to the assistant’s voice and is enabled by default.
If the assistant isn’t hearing you well, turn off ambient sound or lower the ambient volume.

​
8. Endpointing sliders

Control when your assistant starts talking with the endpointing sensitivity slider at the bottom of assistant settings.
If your assistant cuts off callers mid-sentence, increase sensitivity. If responses feel sluggish, decrease it.

​
9. Debug using the call transcript

1

Open Call history

Go to the Call history page in your dashboard.
2

Select your latest test call

Open the most recent call you placed for this assistant.
3

Inspect transcript and function calls

Review the transcript, function calls, and parameters to identify timing or logic issues.
Confirm the assistant is using the expected mode, model, and tools per your configuration.

10. Still have questions?

If you need help, contact our support team via the chat widget inside the app.

​
11. Debug with the Test Assistant (chat)

1

Open your assistant

Open the assistant you want to debug in the Famulor app.
2

Switch to the Test Assistant tab

At the top of the page, click the Test Assistant tab.
3

Start a free chat session

Chat with your assistant to validate prompts, tools, and behavior. These chats are free and do not consume call minutes.
4

Ensure you have chat credits

Make sure you have at least one chat credit available. If you do not have any, go to the credits page and convert your minute credits into chat credits.
