ChatGPT voice and Gemini Live are both free to start and can play an interviewer, which makes them the best general voice assistants for practice. They need a good prompt, they tend to be kind, and neither scores your answers against the job unless you ask. For scored spoken practice built from your résumé, our pick is CoPilot Interview's mock interview, which we make. Most people should use a voice assistant for casual reps and a scored mock for the serious run. Here is how to set up each, the limits you will hit, and how to get a transcript. See the ChatGPT voice guide and the Gemini Live guide.

Setting up a voice assistant
- Start a text chat and paste the job description and your résumé, minus your address and phone number.
- Paste: Act as a hiring manager. Ask one question at a time. Wait until I finish. After each answer, give me one specific fix and ask a follow-up.
- Switch to voice and answer as you would in the room.
- Tell it to stop being encouraging if it starts praising everything.
- Stop after ten minutes, and read the transcript where it is available.
- Ask, in text: what did I say most often, and where did I fail to give a result?
The limits you will hit
- Free voice usage runs out, sometimes without much warning.
- It may interrupt you if you pause, so adjust your settings or use hold-to-talk if offered.
- It tends to agree with you. Ask it to disagree.
- It has no idea what a good answer is in your field unless you tell it.
- It does not know what the employer's interview format will be.
- Noise and accents can affect transcription, so read any transcript with real care.
