Detecta Language Agency is currently recruiting native German speakers from Germany for a large-scale speech data collection project. The objective of this project is to collect and standardize 500 hours of natural full-duplex German conversations to support artificial intelligence and speech recognition technologies.

Recording Specifications
Audio recordings must meet the following technical standards:

• Mobile recording: 24kHz, 16-bit, mono
• Each recording session produces 3 audio files:

• Speaker A audio track
• Speaker B audio track

Both speaker tracks must be perfectly synchronized and represent a natural dialogue between two speakers.

Eligibility
Both experienced professionals and fresh native German speakers are welcome to apply for this project.
