About the role

We’re seeking a skilled Korean Voice Actor to participate in a multi-speaker diarization project, engaging in natural, unscripted group conversations on assigned topics across various domains. In this role, you’ll respond to fellow speakers and contribute to realistic, engaging discussions, using your voice to convey appropriate emotion, personality, and tone.

About the role

As a speaker, you will actively participate in the group conversation and provide clear, natural speech. This is not a solo recording, individual speech sample, or one-person task.

Key responsibilities

Join the assigned session at the exact date, time, and time zone provided. Discuss assigned topics naturally with the other speakers in the session. Speak regularly, respond to others, ask and answer questions, and contribute a fair share of the conversation. Follow the topic guidance and keep the discussion interactive rather than reading a script or giving a formal speech.

Use natural conversational reactions, including brief overlaps and backchannels when appropriate. Candidate requirements Comfortable speaking and interacting in a group conversation. Available for the full assigned session time and time zone. Willing to speak and contribute actively; simply joining and remaining silent is not acceptable.

Able to follow instructions and discuss topics naturally without using a script. Able to provide the required recording environment and microphone setup. Required microphone setup A proper external microphone with wired headphones is preferred. However, a good-quality wired headset with a built-in microphone is also acceptable if it provides clear, muffle-free audio.

A basic or low-quality headset alone is not sufficient. Laptop speakers, Bluetooth earphones, or open speakers are not acceptable during recording. Use the same microphone, headphones, and device for the session which you will be using for the audio sample submission during job application. Record in a quiet room without TV, music, fan noise, traffic, pets, or other people talking.

Position the microphone consistently and speak clearly at a natural volume. Avoid echo, reverb, distortion, clipping, typing, tapping, or handling the device near the microphone. Availability Availability for the exact assigned date, time, and time zone is mandatory. You must be ready to speak and contribute for the full session; simply joining and remaining silent is not acceptable.
