Voice privacy
Starting the microphone check means you agree to the following. You can also answer with text.
Say a few words to check your microphone. This test recording is neither sent to nor saved on the server.
Collection and use
We transcribe spoken answers and summarize their content. We also check microphone input and speech activity. Your voice is not used to identify you or infer emotions or health.
Retention and download
Test audio is deleted after checking. Original answer audio is kept for up to 7 days, then automatically deleted. Transcripts and summaries follow the response retention period stated for the study. Researchers with permission to view original responses and export data can download audio before deletion. Researchers manage any downloaded copies.
Audio processing
We use Microsoft MAI Transcribe 2 through OpenRouter for transcription and an OpenAI model for transcript summaries. Audio or transcripts are sent to these services for processing. See the provider documents below for processing locations and retention policies.
