Your voice. Your infrastructure.
Zero cloud.
Real-time speech recognition with Whisper, neural speech synthesis with F5-TTS and Kokoro, and voice cloning — all running on your hardware, behind your firewall. Not a single second of audio leaves the building.
Full-stack voice,
fully local.
Real-Time Speech Recognition
Whisper on NPU with streaming. Multilingual, low word-error rate even in domain-specific vocabulary. Medical, legal, financial terminology out of the box.
Neural Speech Synthesis
F5-TTS and Kokoro engines. Natural prosody, emotional range, breathing patterns. Indistinguishable from human speech.
Voice Cloning
Clone any voice from a short sample. Your CEO's voice for internal comms, your brand voice for customer interactions. Consent-based, auditable, sovereign.
Multilingual by Default
30+ languages, code-switching within sentences. Accent preservation, dialect awareness. No per-language licensing.
NPU-Accelerated
Runs on Ryzen AI NPU for always-on, low-power inference. GPU not required for standard workloads. Scales from laptop to data centre.
Streaming Pipeline
Sub-200ms first-token latency. Bidirectional streaming via WebSocket and gRPC. Interruption handling, barge-in detection built in.
Where voice
creates value.
Voice Agents for Customer Service
AI phone agents that listen, understand and respond in natural speech. Handle tier-1 inquiries, route complex cases, document everything. 24/7, every language.
Dictation & Documentation
Real-time transcription for doctors, lawyers, engineers. Domain-specific vocabulary, automatic formatting, direct integration into EHR/DMS systems.
Accessible Interfaces
Screen readers, voice navigation, audio descriptions. Making applications accessible to visually impaired users. Compliance with WCAG and EN 301 549.
Brand Voice & Content
Generate training videos, product announcements, internal communications in your own brand voice. Consistent tone across all channels, all languages.
From sound to meaning
and back.
A six-stage pipeline that captures audio, understands speech, processes intent, and responds in natural voice — all locally, all in real time. Sub-second response time end-to-end.
Audio Capture
Microphone input, telephony stream or file upload. Noise cancellation and gain normalisation applied at source.
VAD & Segmentation
Voice activity detection isolates speech from silence. Segments are chunked for streaming inference.
Whisper STT
Speech-to-text via Whisper Large V3. Multilingual transcription with domain-adapted vocabulary.
LLM Processing
Transcribed text is processed by the local LLM for intent recognition, response generation or task execution.
TTS Synthesis
Response text is synthesised into speech via F5-TTS or Kokoro. Voice cloning applied if configured.
Audio Playback
Synthesised audio is streamed back to the client. Sub-200ms latency from text to first audio frame.
Built to
specification.
Whisper Large V3
<50ms chunk latency. WER <5% on domain-adapted data. Streaming and batch modes.
F5-TTS / Kokoro
24kHz output. <200ms first-token latency. Natural prosody with emotional control.
30+ Languages
Real-time code-switching. Accent preservation. Dialect awareness. No per-language licensing.
NPU / GPU / CPU
NPU at 5W for always-on inference. GPU at 50W for peak loads. CPU fallback for maximum compatibility.
WebSocket, gRPC, REST, SIP
Bidirectional streaming. SIP trunk for telephony. REST for batch processing. gRPC for low-latency pipelines.
Zero-Cloud Architecture
No data egress. Encrypted at rest and in transit. Full audit trail on every inference request.
