Let callers interrupt — the agent actually listens

SvaraCall barge-in detects caller speech during agent turns, stops TTS immediately, and processes the new intent — essential for natural Hindi and Telugu conversations.

Problem

Robotic agents talk over customers

Legacy voicebots finish their paragraph while the caller shouts 'stop' or 'haan boliye'. Indian callers expect conversational turn-taking — especially on collections and support calls where emotions run high.

How legacy bots handle interruption

  1. 1Play fixed audio clips — caller must wait for menu to end.
  2. 2Detect DTMF only — speech barge-in unsupported or laggy.
  3. 3Agent repeats from the top after interruption — frustrating loops.
  4. 4Supervisors cannot coach because talk-over ruins recordings.

With SvaraCall

How SvaraCall barge-in works

  1. 1Full-duplex stream monitors caller audio during agent speech.
  2. 2VAD detects caller voice — TTS stops within milliseconds.
  3. 3ASR captures the interruption and routes to intent handling.
  4. 4Agent responds to the new input without restarting the script.

Why barge-in matters in India

  • Natural feel

    Conversations flow like human telecallers — not lecture mode.

  • Faster resolution

    Callers correct the agent immediately — fewer wrong-path minutes.

  • Higher containment

    Less hang-up when people can jump in with 'payment already done'.

  • Cleaner recordings

    Less talk-over noise — better QA and transcription quality.

Barge-in during an EMI reminder

Agent: Namaste, aapka EMI payment 10 August ko due hai, main—
Customer: [interrupts] Main kal pay kar chuka hoon!
Agent: [stops immediately] Ji, dhanyavaad — main abhi check karti hoon. Kya aap transaction ID share kar sakte hain?
Customer: TXN88291.
Agent: Note kar liya. Hamari team verify karegi aur SMS bhejegi.

Enable barge-in on campaigns

  1. Step 1

    Confirm trunk capability

    Full-duplex SIP or CPaaS path required — we validate on pilot.

  2. Step 2

    Tune sensitivity

    Adjust VAD thresholds for noisy mobile networks common in India.

  3. Step 3

    Script for interrupts

    Prompts acknowledge barge-in — 'Ji, sun raha hoon' before new intent.

  4. Step 4

    Measure in analytics

    Track barge-in rate, subsequent containment, and hang-up delta.

Barge-in FAQs

Does barge-in work on mobile networks in India?
Yes. VAD is tuned for typical mobile noise profiles — validated on pilot calls across carriers.
Can we disable barge-in for compliance scripts?
Mandatory disclosure blocks can be marked non-interruptible — configurable per prompt section.
What latency should we expect?
Sub-300ms stop times on supported trunks — measured on Hindi and Telugu production paths.
Does barge-in affect recording quality?
Dual-channel recording captures clean handoffs — less overlap than legacy talk-over bots.
