Speko gives ChatGPT a phone line. Describe the call you want — confirm an appointment, chase a quote, ask a clinic which insurance it takes — and Speko dials the number with a voice agent, stays on the line, and hands back a full transcript and a recording when it ends. Every call opens by saying it is an AI. Before dialing a real person you can rehearse the whole conversation against a synthetic caller and read that transcript first. Speko also transcribes audio from a link, including its own call recordings, and speaks text back in hundreds of voices and languages ChatGPT cannot produce itself.
