Common Issues & Tips for M4A to Text Conversion
High background noise → Decreases accuracy
Noisy environments interfere with recognition. Record in a quiet setting or use a noise-canceling microphone.
Fast speaking pace → System struggles to keep up
Rapid speech may cause missed words. Slow down slightly for important information.
Strong accents or dialects → May challenge software
Mandarin is recognized best. Heavy accents or dialects may lower accuracy—consider tools that support multiple dialects.
Technical terms or proper nouns → Prone to errors
Recognition rates are lower for specialized vocabulary (medical, legal, tech, etc.). Add a custom dictionary or glossary in advance if possible.
Multiple speakers overlapping → Causes confusion
Consider recording separate tracks or using software with "speaker separation" features.
Incompatible recording format or quality
Check the supported formats (e.g., M4A, MP3, WAV) and sample rates (e.g., 16kHz, 44.1kHz) for your chosen tool.

How to Capture High-Quality M4A Audio
in Different Scenarios?
- Use dedicated conference microphones or multi-track recording devices to ensure each speaker is captured clearly.
- Speak close to the microphone and avoid overlapping conversations.
- Turn off noise sources such as air conditioners or printers before recording.
- After the meeting, use noise reduction software or features to enhance audio quality before transcription.
- Use a lavalier microphone or classroom-specific recording equipment placed close to the instructor.
- Opt for mono recording to reduce ambient reverb.
- If there is frequent multi-person interaction, use software with "speaker diarization" to distinguish between the instructor's and students' voices.
- Apply basic noise reduction before importing the audio into transcription software to improve accuracy.
- Ask interviewees in advance to speak clearly in standard Mandarin if possible.
- Use a high-quality microphone or recorder and minimize background noise.
- For specialized topics, create a custom glossary of terms beforehand.
- For long interviews, consider recording in segments by topic to avoid overly long single files that could affect recognition.
