Speko
Speko is a voice AI platform: voice agents that make and take phone calls, with one API across 73 text-to-speech, 54 speech-to-text and 20 speech-to-speech models. Connect it and Claude can make phone calls, transcribe audio, and narrate text. Say “Call this number and ask if they are open on Sunday” and Claude calls from a number on your Speko account, then brings back the transcript and recording. Paste a link and say “Transcribe this Dropbox recording with word timestamps”. Paste a script, pick one of 100+ voices, and get the audio file back. Claude can also build and test voice agents in a simulated conversation (no phone rings), buy a phone number after a short business declaration so an agent takes inbound calls, and turn a Vapi, Retell, LiveKit or Pipecat config into a Speko draft. Sign in once with OAuth; Google or GitHub sign-up works in the flow. No API keys to paste. Start by typing: “Narrate this paragraph in a calm voice.” First prompts for the Use cases step: 1. Call this number and ask if they are open on Sunday. 2. Transcribe this Drive recording and give me word timestamps. 3. Narrate this paragraph in a calm voice and send me the audio file.
