A voice agent feels natural when it answers promptly, doesn’t talk over the contact, and doesn’t leave long silences. This page explains what affects responsiveness on Callers, which settings you control, and how to find the cause when a call feels slow or choppy.

​
What affects responsiveness

Every agent turn has three parts: detecting that the contact has finished speaking, generating a response, and turning it into speech. Several things you configure add time to that loop.

​
Tune patience

Patience Level controls how long the agent waits after the contact stops talking. Open the agent’s voice settings and expand Patience Level. You can also override patience on a single step from the step’s settings. A common pattern:
  • Fast for greetings, confirmations, and small talk.
  • Balanced for most of the script.
  • Slow for steps where the contact reads out a number, spells a name, or thinks about a decision.
If contacts often get cut off mid-sentence, raise patience. If the agent feels sluggish after short answers like “yes,” lower it. Change it in small steps and test after each change.

​
Handle slow actions without dead air

When an in-call action takes more than a moment, the contact hears silence. Use one of these patterns.
In the action step menu, turn on Run in background without pausing the conversation. The agent keeps talking and the response can arrive later in the conversation.Use it when the conversation doesn’t depend on the result right away, for example logging to a CRM or starting a lookup the agent will need a few turns later.
If you don’t see this option in the action step menu, contact support@callers.ai to turn it on.
Also make the API itself fast: return only the fields the agent needs, avoid chaining several slow requests in one action, and add a fallback phrase for errors and timeouts. See Actions.

​
Interruptions

Contacts interrupt for good reasons: they already know the answer, they disagree, or the turn is too long. Some interruptions are accidental, such as background voices or “mm-hm.”
  • Shorten turns first. Long turns are the most common cause of interruptions.
  • Protect only what must be heard. Turn on Speak with no interruptions for disclosures and required lines. Add Only on first play if the step can repeat.
  • Use Auto-Adjust Patience on Interruptions so the agent adapts when a contact interrupts often.
  • Check the step in Insights mode. A high interruption rate on one step usually means it is too long or asks too much.
See Conversation dynamics.

​
Background noise

Noise from traffic, TV, or other people can trigger false interruptions or make speech harder to recognize.
  • Noise Cancelation (agent voice settings): reduces unwanted sounds such as chatter and keystrokes. Choose a level from Basic to Extreme. Higher levels remove more noise but can affect quiet speech, so test with realistic calls.
  • Keypad input is more reliable than speech for digits in noisy settings.
  • Speech recognition vocabulary helps the agent recognize product names and jargon. See Speech recognition vocabulary.
If you don’t see Noise Cancelation in your agent’s voice settings, contact support@callers.ai to turn it on.
Background soundscapes (for example, office ambience) are only available on SIP calls. They make the agent sound more natural but add audio the contact hears. Keep the volume low.

​
Diagnose a slow or choppy call

1

Listen to the recording

Open the call from the agent’s results. Listen for long gaps, the agent talking over the contact, or the agent cutting the contact off. Recordings show timing that transcripts can’t.
2

Read the transcript with timing details

In the transcript, hover the info icon next to a message to see timing details. For agent messages, this shows how long the response took to start generating and to start speaking. For contact messages, it shows speech recognition confidence. Low confidence points to noise, a poor line, or words to add to the vocabulary.
3

Look for tool calls

Find action calls in the transcript. A long gap right after an action means the API is slow. Move it to the background, add a Wait step, or speed up the API.
4

Check Insights mode

Turn on Insights Mode in the agent header to see, per step, how many calls reached it, where contacts hang up, and where interruptions are frequent. Fix the steps with the most drop-offs and interruptions first.
5

Report the issue

If a call shows a problem you can’t fix with settings, report it from the call view. Choose a category such as Speech Interruptions or Speech Recognition. See Reporting call issues.

​
Troubleshooting

Lower Patience Level, or lower it on the specific steps where answers are short. Check whether the step runs an action; if so, run it in the background or add a Wait step with a message.
Raise Patience Level for that step, especially where contacts give long or thoughtful answers. Make sure Auto-Adjust Patience on Interruptions is on.
Shorten the step. If the line must be heard, turn on Speak with no interruptions. If the call is noisy, try Noise Cancelation.
Increase Initiate Conversation After No Response. Make sure the previous step ends with a clear question so the contact knows it is their turn.
Split large documents into smaller, topical items with clear headings. Remove duplicate content. For questions that come up on most calls, write a scenario.
Add them to the speech recognition vocabulary. For digits, use keypad input.
