### Answer Based on the available sources, email capture by voice is acknowledged as challenging. The sources indicate that email capture can be very unreliable, with agents struggling to understand emails correctly, often skipping important parts like "@" or "." when confirming the email, sometimes spelling the email incorrectly, and occasionally switching to English words or responses [(1) ]() . Retell AI is actively working on improvements for email address recognition [(2) ]() . The platform has rolled out major ASR upgrades that bring sharper transcription and stronger intent detection [(3) ]() . For European languages in Accurate mode, Word Error Rate has been cut by 7–10 points, resulting in clearer transcripts even in noisy environments . While the official documentation doesn't provide specific techniques for email capture, community discussions suggest some workarounds: having the AI agent ask users to spell out their email address letter by letter, or using phone numbers as identifiers instead of email addresses [(4) ]() . For capturing email information, you can use dynamic variables to store the data once collected. Dynamic variables allow you to inject personalized data and extract variables in real time during conversations [(5) ]() [(3) ]() .
