AI Voice Agent Development Company in USA

Outbound calling in the US is governed by the TCPA, FCC rules and state law rather than by whether the caller is a person or software. In February 2024 the FCC confirmed that AI-generated voices in robocalls count as artificial voices under the TCPA, which means prior express consent, honouring the National Do Not Call Registry and calling-window rules all still apply. We build the consent record, suppression lists, calling windows and disclosure into the agent, and your counsel signs off on the call flow before it dials. We are engineers, not your attorneys.

Yes. Consent is a design input, not a disclaimer. The agent captures and timestamps consent, checks it against your suppression and Do Not Call lists before dialling, and applies the right recording disclosure per state. Eleven states including California, Florida, Pennsylvania and Washington require all-party consent for recording, so the agent branches on the caller's state rather than reading one script nationwide. Every call leaves an audit record you can produce later.

We target under 800 milliseconds from the caller finishing a sentence to the agent starting its reply, because past roughly a second a caller assumes the line has dropped. That comes from streaming speech recognition, barge-in support so the caller can interrupt, and a text-to-speech voice chosen with you during a listening session. The agent identifies itself as an AI assistant at the start of the call.

Yes, and that is usually where the value is. We integrate with Salesforce, HubSpot, Zoho, ServiceNow, Zendesk, Epic and Cerner via FHIR, Google and Outlook calendars, and custom systems over API. The agent reads live availability, writes the outcome back and leaves a structured summary on the record, so nobody retypes a call afterwards.

The agent transfers, with context. Any caller who asks for a person, becomes distressed, or raises something outside the agent's scope is warm-transferred to your team along with a written summary and the transcript so far, so the customer never repeats themselves. We also set hard escalation rules up front: anything clinical, legal, financial or contractual goes to a human by policy, not by the model's judgement.

A single-purpose agent handling one call type, such as booking or order status, typically runs 18,000 to 35,000 US dollars to build. A multi-intent agent with CRM writeback, payment handling and compliance branching usually falls between 45,000 and 90,000 US dollars. Running costs are per minute of call time across telephony, speech recognition, the model and text to speech, and we model that against your actual call volume before you commit. You get a fixed-price USD scope after discovery.

A focused pilot on one call type is usually live in 6 to 8 weeks, including a shadow-mode period where the agent listens to real calls without answering them. A full production rollout with multiple intents, integrations and compliance branching runs 12 to 16 weeks. Sprint one starts within 7 days of signing.

Yes. Spanish is standard for most US deployments, and we also build agents that handle Mandarin, Tagalog, Vietnamese and Haitian Creole depending on your caller base. The agent detects the language in the first few seconds and switches, rather than making the caller pick from a menu. Each language is tested against real call recordings from your own lines, including accented English, which is where most voice systems actually fail.
