Audio Translation and Analysis Task

I have 4 audio files from a therapist treating a trauma patient. The audio files contain 1 to 2 word phrases and are quite difficult to hear due to low audio and background noise. I need a professional audio translator to identify if the audio contains Japanese words or phrases and their basic meanings, as well as any names or non-Japanese words.

Key Requirements:
- Proficient in Japanese language and culture
- Audio translation and transcription expertise
- Capable of working with low-quality audio
- Able to identify and differentiate between languages, names and non-Japanese words
- Provide a basic meaning of identified Japanese words or phrases

Your task is not to provide a detailed translation, but to give a basic meaning of any identified Japanese words or phrases. You may use any noise reduction tools or advanced audio restoration software at your disposal, but ultimately, I leave it to your expert discretion.
