Frequently Asked Questions
Is AI-generated narration appropriate for academic settings?
Yes, and it is increasingly common. AI narration is used by universities, K-12 districts, and corporate training programs worldwide. OpenAI TTS-HD produces natural-sounding speech that students respond well to, especially for supplementary materials, transcribed lectures, and accessibility content. For face-to-face instruction, nothing replaces a human teacher. But for recorded and asynchronous content, AI narration saves enormous time.
How can voice AI help with accessibility compliance?
Voice AI addresses multiple accessibility requirements. TTS converts written materials to audio for students with visual impairments or dyslexia. Transcription provides text versions of lectures for deaf and hard-of-hearing students. Translation makes content available in students native languages. Together, these capabilities help institutions meet ADA Section 508, WCAG 2.1, and international accessibility standards.
Can I transcribe recorded Zoom or Teams lectures?
Yes. Download the recording from Zoom or Teams as an MP3, M4A, or MP4 file. Upload it to KAZI Voice Studio for transcription. You get a full transcript with speaker identification, timestamps, and 99%+ accuracy. Export as plain text for study notes or SRT for subtitled video. The entire process takes about 2 minutes for a 1-hour recording.
How much does it cost for an entire semester of course narration?
With browser TTS (free tier), narration costs nothing. With premium voices via BYOK, a typical 15-week course with 3 hours of narrated content per week (~45 hours total) costs approximately $40-$80 at OpenAI TTS-HD rates. Compare this to thousands of dollars for professional narration or the hundreds of hours of faculty time for self-recording. KAZI cost tracking monitors every generation.
Can multiple instructors share a KAZI account?
KAZI Pro supports team features. Multiple instructors can access the Voice Studio under one account. Each instructor can have their own voice clone for personalized narration. Project management features help organize materials by course, semester, and department. Admin controls let you manage API keys and monitor usage across the team.
