Everything you need
to build Voice AI.
One platform. Every primitive. From simple FAQ bots to complex, action-taking enterprise agents — running across any channel at any scale, billed per second of actual usage.
One agent.
Every channel.
Define your conversational agent once. The same logic, knowledge base, and tool integrations deploy across all six channels simultaneously — without rewriting anything.
Phone / PSTN
Provision real inbound DID numbers or run outbound campaigns. Supports US, UK, India, and 50+ countries.
Inbound routing, IVR override, call transfer, DTMF, voicemail detection
SIP Trunk (BYOC)
Connect your existing carrier infrastructure. Full SIP/RTP control with custom routing rules.
RFC 3261 compliant · TLS/SRTP · G.711/G.722/Opus codecs
Web Voice Widget
Embed a fully branded voice agent on any website or app with a single JS snippet.
WebRTC · Floating widget · Customizable UI · Mobile-first
WhatsApp Voice
Deploy voice agents inside WhatsApp Business flows with fallback to text responses.
WhatsApp Business API · Media messages · Template integration
WebSocket API
Stream raw audio in/out using WebSocket. Build custom integrations with your own audio pipeline.
Binary audio frames · Bidirectional · Low-latency · Serverless-compatible
Outbound Dialer
Launch high-throughput parallel dialing campaigns with AMD, retry logic, and CRM sync.
AMD detection · Local presence · Voicemail drop · Real-time reporting
Every building block.
Fully composable.
Mix and match platform primitives to build exactly the voice experience your product needs — no vendor lock-in, no black boxes, pay only for what you use.
Dynamic Workflows
Design complex conversational flows with conditional branching, loops, variable injection, and context-aware logic. The agent adapts its path in real-time based on user intent, slot values, and live API responses.
- Visual flow builder
- Conditional logic & loops
- Context variable injection
- A/B test variants
- Fallback & escalation paths
Knowledge Base (RAG)
Upload documents, FAQs, product manuals, and URLs. Converse indexes everything with vector embeddings and retrieves the most semantically relevant context in real-time during a call — with perfect recall and zero hallucination on factual data.
- PDF, DOCX, URL, CSV ingestion
- Hybrid semantic + keyword search
- Auto-chunking & reranking
- Source citation in transcripts
- Incremental sync & updates
Custom Tool Calling
Give your agent the ability to take real actions. Fire webhooks, call REST APIs, query databases, or execute custom code mid-conversation. Book meetings, process payments, update CRMs — all without interrupting the natural flow of the call.
- HTTP/webhook integrations
- Async long-running tasks
- Retry with exponential backoff
- Parameter type validation
- Secure secret injection
Live Spaces
Monitor every active agent call in real-time from a unified supervisor dashboard. Listen in silently, view the live transcript and per-turn sentiment, and seamlessly take over with human handoff when the situation requires it.
- Silent call monitoring
- Live transcript + sentiment
- 1-click human handoff
- Barge-in capability
- Multi-agent supervisor view
Analytics & Observability
Every call produces a rich dataset. Full verbatim transcripts, per-turn intent classification, sentiment curves, CSAT prediction, conversion tracking, and call quality scores — all queryable from the dashboard or exportable via API.
- Full call transcripts
- Sentiment & intent per turn
- Conversion & containment rates
- CSAT prediction scoring
- Export to BigQuery / S3 / webhook
Voice & Localization
Deploy in 30+ languages with authentic regional accents. High-fidelity 48kHz TTS synthesis with emotion modeling, custom voice cloning from 30 seconds of audio, and code-switching support (e.g., Hinglish, Tanglish).
- 30+ languages & regional accents
- 48kHz premium TTS
- Zero-shot emotion transfer
- Code-switching (Hinglish etc.)
- Voice cloning in 30 sec
Telephony Built-In
Provision real phone numbers for inbound support or run massive outbound dialer campaigns directly from the platform. Full SIP support lets you bring your own carrier for custom routing and cost control.
- 50+ country DID numbers
- High-throughput outbound dialer
- AMD voicemail detection
- BYOC SIP / PSTN trunking
- Call recording & compliance
Enterprise Security
Built for regulated industries. HIPAA and PCI-DSS compliant architecture with end-to-end encryption, strict data residency controls, SSO integration (Okta, Google), full audit logs, and a granular RBAC permission model.
- HIPAA & PCI-DSS compliant
- End-to-end call encryption
- Data residency (US, EU, IN)
- SSO + SCIM provisioning
- RBAC & audit trail
Developer-First APIs
Complete programmatic control over every platform primitive. Manage agents, trigger calls, stream audio, and query analytics via REST and WebSocket APIs. Full OpenAPI spec and client SDKs for Node.js, Python, and Go.
- Full REST + WebSocket APIs
- Node.js, Python, Go SDKs
- OpenAPI / Swagger spec
- Webhook event streaming
- Postman collection
Sub-300ms Latency
Our entire STT → LLM → TTS pipeline is parallelized and co-located at the edge. Speech recognition begins before the user finishes speaking. Average end-to-end latency is ~250ms, making conversations feel completely natural.
- Parallel STT/LLM/TTS pipeline
- Edge co-location
- Predictive speech detection
- ~250ms avg end-to-end
- Adaptive quality scaling
Voice Cloning
Clone any voice from just 30 seconds of audio. Deploy your brand's voice, a specific persona, or a real agent's voice across all AI agents. Zero-shot emotion adaptation means the clone responds naturally in any conversational context.
- 30 sec audio sample
- Zero-shot emotion transfer
- Multi-language support
- Persona management
- Usage-based billing
Multichannel Deployment
Define your agent once, deploy everywhere. The same conversational logic, knowledge base, and tool integrations work identically across Phone, SIP, Web Widget, WhatsApp, WebSocket API, and Outbound Dialer.
- Single agent config, 6 channels
- Channel-aware routing
- Unified analytics across channels
- Per-channel voice & language
- Graceful fallback logic
How a call works,
inside Converse.
Inbound / Outbound
Call arrives via Phone, SIP, Web Widget, or API. The channel adapter normalises the audio stream.
Speech-to-Text (STT)
Parallel streaming STT converts the caller's speech to text in real-time with <50ms word latency.
LLM + Workflow Engine
The context engine runs the workflow, queries the Knowledge Base, and calls any configured tools.
Text-to-Speech (TTS)
The response text is streamed to a 48kHz TTS engine and the first audio chunk plays within ~250ms.
Analytics & Logs
Every turn produces a transcript, sentiment score, tool log, and call quality metric — stored instantly.
The Sub-300ms Advantage
Voice AI breaks down when latency exceeds 500ms — conversations feel robotic, unnatural, and frustrating. We engineered our entire STT → LLM → TTS stack to operate in parallel, co-located at the edge, so responses feel instantaneous.
- Streaming STT starts transcribing before the speaker finishes
- LLM inference begins as soon as first utterance tokens arrive
- First TTS audio chunk plays within 250ms of speaker finishing
- Adaptive bitrate scaling for poor network conditions
