 #### Best Practices for Speaker Diarization
-- **Clear Audio**: Use high-quality recordings for better accuracy
-- **Speaker Separation**: Ensure speakers don't talk simultaneously
-- **Minimum Duration**: Each speaker segment should be at least 2-3 seconds
-- **Audio Format**: Use M4A, MP3, or WAV for optimal results

 ## Troubleshooting
 
 ### Common Issues
 
 #### "Invalid API Key" Error
+
 **Solutions:**
+
 1. Verify API key format (OpenAI: starts with `sk-`)
 2. Check API key status on provider dashboard
 3. Ensure sufficient credits/active subscription
 4. Remove any extra spaces from key
 
 #### "File too large" Error
+
 **Solutions:**
+
 1. Check file size limits (Whisper: 25MB, Deepgram: 2GB)
 2. Use Deepgram for larger files
 3. Compress audio files if needed
 
 #### Speaker Diarization Not Working
+
 **Solutions:**
+
 1. Ensure Nova-3 model is selected (required for diarization)
 2. Check "Speaker Diarization" is enabled in Deepgram settings
 3. Verify audio quality (clear speakers, minimal overlap)

 5. Check minimum speaker duration (2-3 seconds per segment)
 
 #### No Audio Files Found
+
 **Solutions:**
+
 1. Verify supported formats: .m4a, .mp3, .wav, .mp4, etc.
 2. Ensure files are in vault folder
 3. Restart Obsidian
 4. Wait for file indexing (large vaults)
 
 #### Network Errors
+
 **Solutions:**
+
 1. Check internet connection
 2. Verify VPN/proxy settings
 3. Check provider API status

 ## 문제 해결
 
 ### 일반적인 문제
 
 #### "Invalid API Key" 오류
+
 **해결 방법:**
+
 1. API 키 형식 확인 (OpenAI: `sk-`로 시작)
 2. 공급자 대시보드에서 API 키 상태 확인
 3. 충분한 크레딧/활성 구독 확인
 4. 키에서 공백 제거
 
 #### "File too large" 오류
+
 **해결 방법:**
+
 1. 파일 크기 제한 확인 (Whisper: 25MB, Deepgram: 2GB)
 2. 큰 파일은 Deepgram 사용
 3. 필요시 오디오 파일 압축
 
 #### 화자 분리가 작동하지 않음
+
 **해결 방법:**
+
 1. Nova-3 모델이 선택되었는지 확인 (화자 분리에 필요)
 2. Deepgram 설정에서 "Speaker Diarization"이 활성화되었는지 확인
 3. 오디오 품질 확인 (명확한 화자, 최소 중첩)
@@ -758,34 +828,40 @@ Speaker 3: 마감일을 일주일 연장해야 할 것 같습니다.
 5. 최소 화자 길이 확인 (세그먼트당 2-3초)
 
 #### 오디오 파일을 찾을 수 없음
+
 **해결 방법:**
+
 1. 지원 형식 확인: .m4a, .mp3, .wav, .mp4 등
 2. 파일이 vault 폴더에 있는지 확인
 3. Obsidian 재시작
 4. 파일 인덱싱 대기 (큰 vault의 경우)
 
 #### 네트워크 오류
+
 **해결 방법:**
+
 1. 인터넷 연결 확인
 2. VPN/프록시 설정 확인
 3. 공급자 API 상태 확인
