I wrote the following sentence. It is a point listed in my CV to show my work in one project related with my major computer science. I am applying for a graduate university. The missing subject of the sentence is "I". Because the succinct form in CV, all the pointed I listed ingorns the subject. I think the form is very common in CV. You can see the words after "using" as one kind of technology in computer science.
“Performed speech transcription for course recordings using a recognition framework based on a deep fully convolutional neural network”
I want to express that I converted the course recordings to text. I am not sure whether it is redundant to use “speech” and “recordings” in “performed speech transcription for course recordings” because the two words seem to have the same meaning. If it is redundant, how about using “performed course recordings transcription using a computer technology”? And does “performed course recordings transcription” express the same meaning with my old expressions?
Response to the comment
The speech transcription is actually one function of the class assistant app I have developed. So I think maybe I can write
“Implemented a digital speech transcription service to transcribe recordings of courses using a recognition framework based on a deep fully convolutional neural network”.
May I ask that can this new sentence convey my initial meaning clearly?
