Voice AI Development
Not every voice AI project is a talking agent. A great deal of value sits in the calls you already record and never analyse.
Your call recordings are an unread dataset
Most organisations record every call for compliance and listen to a fraction of one percent.
Inside that archive is every objection your prospects raise, every complaint pattern, every competitor mentioned, every promise a rep made that nobody logged, and every compliance disclosure that was or was not given.
Voice AI turns it into a searchable, scorable dataset. That is often a faster payback than a talking agent, and considerably less risky to deploy.
- Every call transcribed, diarised and searchable
- Compliance disclosures checked on 100% of calls, not a sample
- Objection and competitor mentions tracked over time
- Commitments extracted and written to the CRM
- Quality scoring applied consistently rather than by supervisor availability
- Sentiment and escalation-risk trends by team and by queue
Voice AI applications
Call transcription and search
Every conversation searchable by phrase, speaker and topic.
Compliance monitoring
Required disclosures verified on every call rather than a sample.
Sales call analytics
Talk ratio, objection patterns, competitor mentions and next-step commitment.
Quality assurance
Consistent scoring across all agents against your rubric.
Meeting summarisation
Notes, decisions and actions extracted and distributed.
Voice biometrics
Speaker verification for authentication, subject to consent and local law.
Real-time agent assist
Suggested answers surfaced to the agent during a live call.
Ten stages from first call to a system your team trusts
Every AI engagement runs this sequence. Small projects compress stages; regulated projects expand them. Nothing gets skipped silently.
Discovery
A working session with your operations and engineering leads to map the process, the systems it touches, and where the cost actually sits.
AI Opportunity Assessment
We score candidate use cases on data readiness, volume, error tolerance and payback, then rank them. Some come back "do not use AI for this" — you get that answer too.
Solution Architecture
Model selection, retrieval design, tool boundaries, data flow, failure modes and hosting topology, documented before code.
Proof of Concept
A narrow build against your real data to prove accuracy on the cases that matter, typically 2–4 weeks. Go / no-go decision at the end.
MVP
One workflow, end to end, in the hands of real users. Evaluation sets and quality thresholds are defined here, not retrofitted.
Production Development
Hardening: error handling, retries, fallbacks, cost controls, rate limits, observability, and a human escalation path for every automated decision.
Integration
Wiring into your CRM, ERP, HRMS, data warehouse, ticketing and messaging channels through APIs, webhooks and event queues.
Security Testing
Prompt-injection testing, access-control verification, PII handling review, dependency scanning and penetration testing before go-live.
Deployment
Staged rollout on your cloud or ours, with CI/CD, versioned prompts and models, and rollback in place from day one.
Monitoring & Optimization
Quality dashboards, drift detection, cost-per-transaction tracking and a retraining or re-prompting cadence agreed in writing.
Security-conscious architecture, from the first design review
Enterprise AI fails on governance more often than on models. Every system we build is designed to support enterprise security requirements and to give your risk team answers rather than assurances.
Data privacy & residency
Your data stays in the region and tenancy you nominate. We architect for no-training-on-your-data configurations and document exactly which vendor endpoints see which fields.
Role-based access control
Retrieval and tool permissions inherit your existing roles. A user cannot surface a document through the AI that they could not open directly.
Authentication & authorization
SSO via OIDC/SAML, short-lived tokens for agent tool calls, and per-tool scopes so an agent holds the narrowest possible privilege.
Encryption
TLS in transit, AES-256 at rest, managed keys via your cloud KMS, and encrypted vector stores for embedded content.
API security
Gateway-level authentication, signed webhooks, IP allowlisting, request validation and quota enforcement on every exposed endpoint.
Audit logging
Every prompt, retrieval, tool call, model version and human override is logged with a trace ID, so any output can be reconstructed months later.
Data isolation
Per-tenant separation at the storage, index and key level for multi-entity groups and regulated environments.
Secure prompt handling
System instructions are server-side, user content is treated as untrusted input, and we test against prompt-injection and tool-abuse patterns.
PII protection
Detection, masking or tokenisation of personal data before it reaches a model, with configurable redaction policies per field.
Human approval workflows
High-impact actions — payments, refunds, contract sends, record deletion — route to a named approver instead of executing autonomously.
Monitoring & anomaly detection
Alerting on unusual tool usage, cost spikes, refusal rates and quality regressions.
Rate limiting & abuse control
Per-user and per-tenant throttles, spend caps and circuit breakers so a runaway loop cannot become a runaway invoice.
Secure deployment
Private networking, secrets in a managed vault, immutable builds, dependency scanning, and infrastructure as code.
Questions enterprise buyers ask us first
How accurate is speech recognition on real calls?
Can it transcribe multiple languages?
Is voice biometrics legal for authentication?
Can this work on live calls, not just recordings?
