What is voice data?

Voice data is a collection of recordings of people speaking, usually following a script or a set of instructions. The recordings are used to teach software to understand speech.

Common project types

• Dialect and accent recordings
• Free conversations

What you need

• A quiet room
• A phone or a microphone
• A clear, steady voice
• Your native language or dialect

Follow the specs

Each project has its own rules: file format (often WAV), sample rate, naming, and length. Always follow them exactly. A typical list is in preparing voice recordings for data projects.

Where to look for work

• Data collection companies
• Freelance platforms
• Trusted agencies
• Communities of recorders

Be careful: never pay to get work

Real projects do not ask you to pay a fee to join. If someone asks for money before giving you work, treat it as a warning sign.

Before you submit

• Check the audio quality.
• Name the files correctly.
• Deliver on time.
