[Glossary](https://telxpress.com/glossary/) / Voice # AI voice agent An **AI voice agent** is software that answers phone calls in natural conversation, understands what the caller wants, answers questions, books appointments and transfers or takes messages when a person is needed. - Voice - Updated October 11, 2026 - Written by the Telxpress advisory team 01 In depth ## What it is, why it matters and *what to ask a vendor* An AI voice agent combines speech-to-text, a language model and text-to-speech so it can hold a real conversation on the phone. Unlike an auto attendant it does not present a menu; it listens, asks qualifying questions, looks up or records information in your systems and completes tasks such as scheduling. For a growing business the value is every call answered, including after hours and when the whole team is busy. Missed calls become booked appointments and captured leads, and the transcript shows what callers actually ask for. Donya, the agent Telxpress builds and runs, is one example of this category. Ask a vendor how the agent discloses that it is an AI, what happens when it cannot help, how it hands a caller to a person with context, which systems it writes to, how recordings and transcripts are stored, and who tunes it after launch. Hear it handle a call before you sign. 02 Related terms ## Terms that usually come up *alongside it* - Voice ### [AI receptionist](https://telxpress.com/glossary/ai-receptionist/) An AI receptionist is an AI voice agent configured for front-desk work: greeting callers, answering routine questions, routing calls to the right person and scheduling, so staff handle visitors and exceptions. - Voice ### [Auto attendant](https://telxpress.com/glossary/auto-attendant/) An auto attendant is the recorded phone menu that greets callers and routes them by keypad or spoken choice (press one for sales), without a live person or a conversation. - Voice ### [Warm transfer](https://telxpress.com/glossary/warm-transfer/) A warm transfer hands a caller to a colleague only after the person transferring has spoken to that colleague, passed on the caller's name and reason, and confirmed they are ready to take the call. - Voice ### [Speech-to-text](https://telxpress.com/glossary/speech-to-text/) Speech-to-text (STT) is the technology that converts spoken words into written text in real time; it is the first stage of an AI voice agent and the basis of call transcripts, captions and meeting notes. - Security & compliance ### [Call recording consent](https://telxpress.com/glossary/call-recording-consent/) Call recording consent is the permission the law requires before a phone call is recorded; in California, every party to a confidential call must be told and agree, which is often called two-party consent. 03 At Telxpress ## Where this shows up *at Telxpress* The pages and articles where this term does real work: what we advise, build and support. - Page ### [Donya AI Voice Agent: Never Miss a Call](https://telxpress.com/solutions/ai/voice-agent/) Donya answers every call 24/7, qualifies leads and books appointments.
