  • Call recording guide
Transcription

Transcription (ASR) turns live audio into structured text so teams can search conversations, trigger logic, and build analytics.

  • Extract caller intent and key phrases for downstream workflows.
  • Improve Voice AI quality with transcript-based analysis loops.
  • Support text-based monitoring and reporting across campaigns.

Run Text-to-Speech in VoxEngine

VoxEngine TTS gives you direct control over how your AI voice sounds and responds across call flows.

  • Tune voice output for clarity and brand consistency.
  • Use this model in half-cascade architectures where output is provider-flexible.
  • Keep low-latency, interruption-friendly responses for live calls.

  • Realtime TTS guide
Playback audio

Audio playback lets you deliver branded prompts, disclaimers, and dynamic messages as part of production call experiences.

  • Play pre-recorded or generated audio at key points in the call journey.
  • Use prompt playback for onboarding, queue messaging, and compliance notices.
  • Combine playback with AI-driven logic for hybrid call flows.

Playback links:

  • Media player guide
Add Click-to-call

Click-to-call is a fast path to embed calling in web experiences like onboarding, support, and sales journeys.

  • Let users initiate calls from your website or app with minimal friction.
  • Use browser entry points to connect web traffic directly into Voice AI call flows.
  • Accelerate proof-of-value for product and customer teams.

Use Call Lists

Call Lists let you upload target contacts and automate outbound dialing flows for campaigns, follow-ups, and scheduled outreach.

  • Launch large outbound initiatives without manually triggering each call.
  • Connect list-based dialing with your Voice AI scenarios for qualification and handoff.
  • Combine with campaign logic to monitor progression and optimize throughput.

Work with WebSockets

WebSocket media streams let you connect Voximplant calls to custom real-time services and data pipelines.

  • Stream audio and events to external AI or analytics backends.
  • Build provider-specific integrations beyond out-of-the-box connectors.
  • Keep telephony orchestration in VoxEngine while extending media processing.

WebSockets links:

  • WebSocket media streams guide
Conferencing

Conferencing expands one-to-one interactions into collaborative call experiences across customers, agents, and AI participants.

  • Add specialist, supervisor, or handoff participants when needed.
  • Bridge PSTN, SIP, and WebRTC participants into one session.
  • Support richer assisted-service and hybrid human+AI workflows.

Use Dialogflow (State-Machine oriented Voice AI)

Dialogflow is a strong fit for deterministic conversation design where intents, states, and transitions are explicit and controlled.

  • Build predictable call journeys for regulated or policy-driven flows.
  • Combine intent/state routing with Voximplant telephony capabilities.
  • Run IVR-like and virtual-agent experiences with clear control logic.
