Convert speech to text for analysis and automation.
Control agent voice playback and response style.
Play prompts, messages, and media clips in live call flows.
Launch browser-to-phone journeys for onboarding and support.
Run outbound campaigns using uploaded contact lists.
Stream media and events for advanced real-time integrations.
Bring multiple participants and AI into one call experience.
Build structured state-machine voice journeys.

Recording
Recording helps teams review outcomes, improve prompts, and support operational/compliance workflows.
- Capture and review real conversations to improve prompts and call handling.
- Use recordings for QA workflows and stakeholder reviews.
- Preserve call evidence for internal audits and escalations.
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.
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.
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.
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.
