Build and run AI agents for voice, SMS, chat, and web-based conversations on one platform. Support live interactions with low-latency runtime behavior, provider flexibility, and mission-critical operational discipline.
One agent connected to phone, SMS, web, and operator surfaces.
Syllable is designed for conversational systems that have to work across more than one channel. Teams can support voice, SMS, chat, and web-based interactions without rebuilding the core runtime for each delivery surface.
That makes it easier to keep behavior, guardrails, and operational visibility consistent across the customer journey.
A channel map showing voice, SMS, chat, and web sessions feeding into one operational layer.
A real-time voice flow with SIP/PSTN connectivity, turn-taking, transcription, reasoning, and audio delivery.
Current public product materials point to support for local and toll-free phone numbers, SIP and PSTN connectivity, and web-based voice experiences through WebRTC. The runtime is built for streaming audio, interruption handling, turn-taking, and sub-second conversational responsiveness where live voice quality matters.
Recorded and transcribed calls also create an operational record teams can use for review, compliance, and optimization.
Voice is only one part of the customer experience. Syllable also supports SMS, chat, and web-based interactions so teams can carry the same workflows, escalation paths, and visibility into asynchronous or browser-based channels.
This helps teams build follow-up, scheduling, support, and outreach experiences that feel connected instead of fragmented by channel.
An SMS thread, a web chat session, and a web voice experience sharing one policy and monitoring layer.
Language badges across the same agent deployment.
Current public product material points to support for English, Spanish, Arabic, Russian, and French in live agent experiences. Multilingual support helps teams deliver access across contact-center, patient, student, and service workflows without standing up separate systems per language.
Communications workloads change fast. Syllable gives teams a more neutral operating model across model, speech, and voice providers so routing, failover, and quality decisions can evolve without forcing a full platform rewrite.
That preserves leverage while helping teams protect experience quality and resilience in production.
Voice and messaging providers connected through a gateway layer with failover paths.
Compliance and security callouts layered over live conversational traffic.
Real-world communication systems need trust built in. Current trust-center materials point to encryption at rest and in transit, audit logging, continuous monitoring, penetration testing, vulnerability scans, and compliance-oriented controls.
Build and run voice, SMS, chat, and web agents on the trusted neutral platform.
