Selection tips & next steps
Audio quality directly impacts transcription accuracy, so invest in external microphones, conduct interviews in quiet environments, and record locally when possible to avoid compression artifacts. For healthcare and PII-sensitive research, verify SOC 2/ISO certifications and require HIPAA business associate agreements where applicable. Always align data retention and residency policies with your data processing agreements.
