Voice Agent Development

We build voice agents that handle real call workflows: answer questions, collect details, book appointments, and complete actions via tools—while keeping latency low and human handoff seamless. Delivery aligned to United Kingdom teams (GBP).

Security-first AI integrations • Evals + logging + guardrails included

Overview

What this service is

Voice agents combine telephony with real-time STT/TTS and tool access to complete workflows over calls.

We design call flows with safety and compliance in mind: consent, escalation, and strict action allowlists.

Delivery includes monitoring for latency, failures, and user outcomes so you can iterate confidently after launch.

Standard

AI delivery standard

Quality and safety practices we ship with AI builds so the system stays measurable, maintainable, and production-ready.

Logging + tracing

Conversation and tool traces with request IDs, error visibility, and debug-friendly runbooks.

Guardrails + safety

Tool allowlists, PII-safe patterns, refusal behavior, and escalation routes for edge cases.

Evals + regression tests

Golden queries, scorecards, and regression checks so quality improves over time instead of drifting.

Cost + latency controls

Caching, prompt discipline, retrieval tuning, and routing so your app stays fast and predictable at scale.

Documentation + handoff

Architecture notes, environment setup, and next-step roadmap so your team can iterate safely after launch.

Security-first integration

Secrets isolation, role-based access, audit-friendly actions, and minimal data retention by design.

Benefits

What you get

Features

What we deliver

Inbound and outbound call flows

Greeting, intent detection, verification steps, and outcomes (book, route, resolve) with robust fallback behavior.

Real-time STT/TTS

Low-latency transcription and natural speech synthesis tuned for your brand and call environment.

Knowledge grounding (optional RAG)

Answer from your policies and docs with citations available in transcripts and post-call summaries.

Tool actions

Create tickets, book appointments, update CRM fields, and trigger workflows via allowlisted tools and approvals.

Human transfer + agent assist

Warm transfer with a structured summary, extracted fields, and call transcript so humans continue smoothly.

Observability + evaluation

Latency metrics, failure tracking, call outcome dashboards, and regression checks on common intents.

Use Cases

Who this is for

Appointment scheduling agent

Handle inbound calls, check availability, book appointments, and send confirmations automatically.

After-hours lead capture

Qualify callers, capture structured requirements, and route leads with summaries to your team.

Tier-1 support hotline

Resolve common issues and create tickets with details when escalation is needed—reducing agent load.

Collections and follow-ups

Run compliant outbound workflows with opt-outs, scripting, and clear audit trails.

Internal ops call assistant

Summarize calls, extract action items, and create tasks automatically for faster follow-through.

AI Case Examples

Micro case studies (anonymous)

A few safe examples of outcomes we build for real operations—no client names, just results.

Secure Mobile Solution in Australian Defence Ecosystem

Problem: Secure data workflows were required in a regulated environment with strict access controls.

Solution: Hardened architecture with strict auth, encrypted storage, and audit-friendly engineering patterns.

Outcome: Deployed securely within a regulated ecosystem with clear handoff and operational guidance.

AI Knowledge Base Across 2,000+ Pages

Problem: Teams needed fast answers across long PDFs, but search was slow and results were inconsistent.

Solution: RAG with hybrid retrieval and reranking, plus grounded answers and safer fallback behavior.

Outcome: Reliable answers with <10s response times and measurable improvements on real queries.

Ops Automation with AI + n8n

Problem: Manual approvals and CRM syncing created delays and data inconsistencies across tools.

Solution: Event-driven automation with validation gates and AI-assisted classification where it improved routing.

Outcome: Reduced manual workload significantly with more reliable workflows and operator visibility.

FAQ

Frequently asked questions

We use streaming STT/TTS, tight prompt/tool routing, caching where appropriate, and careful model selection to keep responses fast and conversational.

Yes. We implement warm transfer with a summary and transcript so humans have context immediately.

Yes, where allowed. We design outbound flows with compliance and opt-out handling based on your region and policies.

Yes. We can book appointments, update CRM records, and create tasks via API integrations and tool allowlists.

We can support recording where appropriate. Recording policies and consent requirements vary—so we implement clear consent flows and configurable retention rules.

Start with 2–3 core intents (scheduling, FAQ, lead capture) and a clean human handoff, then expand based on analytics.

Regional

Delivery considerations for your region

Compliance & Data (UK/EU)

For UK teams, we default to GDPR-first thinking: data minimisation, purpose-limited storage, and clear access boundaries.

We can work under a DPA (template available on request) and implement practical retention/deletion flows when needed.

  • GDPR-first patterns (minimise, restrict, document)
  • DPA template available on request
  • Retention/deletion and export flows where required
  • Least-privilege access and secure session handling
  • PII-safe logging + secure-by-default configuration
  • NDA available for early-stage discussions

Timezone & Collaboration (UK/EU)

We align to UK time and EU overlap (GMT/BST with CET-friendly windows) for fast feedback cycles.

We keep the process lightweight: async updates, clear priorities, and written decisions to avoid ambiguity.

  • UK/EU overlap with GMT/BST windows
  • Async-first delivery with documented scope
  • Weekly milestones and structured demos
  • Clear escalation path for blockers
  • Tight change control with clear sign-offs

Engagement & Procurement (UK)

We support typical UK procurement flows with clear scopes, change control, and invoice cadence.

If you prefer a discovery-first engagement, we can run a short paid discovery to lock requirements before build.

  • GBP-based engagements and invoicing options
  • Discovery-first option to reduce delivery risk
  • Milestone-based billing when appropriate
  • Transparent change control and sign-offs
  • Vendor onboarding pack on request

Security & Quality (UK/EU)

We build for reliability and maintainability: clean PRs, tight review loops, and test coverage that matches risk.

Performance budgets and release checklists keep launches predictable—especially when multiple stakeholders review changes.

  • CI-friendly testing: unit + integration + smoke tests
  • Performance budgets + bundle checks (Core Web Vitals-minded)
  • Structured release notes and rollback-safe deployments
  • Security checklist for auth, roles, and data flows
  • Observability hooks (logs + error tracking) ready for production
