Start with permission to use the workflow

Polyglot can transcribe an authorized student video assignment on an Apple Silicon Mac, let you review the text alongside playback and export separate SRT, WebVTT or text files. Use this workflow only when your assignment permits the tools and processing involved. It starts with your existing recording; Polyglot does not create an answer, record a presentation, grade work or submit it to a learning platform.

Read the assignment brief before importing the file. Check whether AI transcription, translation, external editing and assistance from another person are allowed. Permission to add captions does not automatically permit translating an assessed language performance or rewriting what you said. If the brief is unclear, ask the instructor or the institution’s accessibility service for the approved process first.

Cornell’s teaching guidance illustrates why this check matters: instructors should make permitted AI use and documentation expectations clear for each course or assignment. Its example policies are not a universal permission to use Polyglot. An institution may require its own captioning service or platform; follow that requirement. Keep any required tool-use declaration separate from the spoken captions.

Keep the brief, permitted take and caption file together

Create a small submission-integrity sheet outside the app. Record the assignment identifier, brief revision, exact video filename, caption language, allowed processing and intended recipients. Note whether the rules require one continuous take, allow edits or allow another recording. A polished replacement is not interchangeable with the permitted assessed take.

Use your own recording or material you are authorized to process. For group work, confirm permission for the other participants and follow the course’s rules for shared contributions. Check included clips, slides and music before sharing. Use the institution’s required identifier rather than adding unnecessary student names or marks to filenames.

Local media processing does not control access after upload. Keep the video, subtitles and any exported transcript within the same approved submission boundary. If peer review is part of the task, verify which classmates may see it; otherwise do not make the recording public to solve an access problem.

Correct the transcription, not the answer

Listen to each cue with the submitted recording. Restore words that recognition missed and correct text that misrepresents the sound. Do not replace an incorrect spoken claim with the answer from your notes. A slide, script or textbook can help identify a term, but it cannot establish that you actually said it.

W3C’s transcription guidance distinguishes faithful transcription from correcting a speaker’s grammar or mistakes. For an assessed recording, preserve meaningful hesitation, self-correction and qualifications according to the assignment’s caption brief. Do not silently remove evidence of the performance just because a shorter sentence reads better.

This fictional review note separates two different errors. The first is a transcription mistake that should be corrected. The second belongs to the recording. If rerecording is permitted, make a new take and review its captions; if it is not, keep the captions faithful and use the institution’s allowed clarification process.

Keep language help within the agreed scope

Check that the recording’s language is supported for transcription; translation targets are a separate capability. Review the original text before making any permitted translation. If the assessment measures language ability, do not assume a translated or grammatically improved track is an acceptable submission. Follow the approved accommodation or assessment instructions.

Where another language track is explicitly allowed, have a competent reviewer check meaning, uncertainty, numerical claims and references to the work. The translation should not add a missing argument or make an uncertain statement sound conclusive. Keep the original recording and track identifiable as the assessed source.

Review speaker context and meaningful sounds manually when they are needed to understand the recording. A spoken “this result” beside an unlabeled chart may also need an approved visual description or companion document. Speech transcription does not supply that description, identify speakers automatically or establish complete accessibility. Finish missing caption events in a suitable editor.

Check the exact submission the assessor will open

Export the reviewed SRT or WebVTT format accepted by the receiving player. Pair it with the exact permitted video and language through that platform’s own controls. If students cannot attach caption files, ask for the approved handoff rather than assuming a separate attachment will display automatically. Polyglot does not burn captions into video, upload assignments, set permissions or connect to a gradebook.

Panopto describes institution-managed recording and submission workflows with captions and LMS assessment features. Those are the platform’s capabilities. If your course already provides a suitable workflow, use it; a separate local editor is useful only when the course permits it and accepts its output.

Use the institution’s permitted preview or test-view procedure to check that the assessor can open the video and select the intended track. Watch the beginning, a self-correction, a slide reference and the ending. Seek into the middle, check caption timing and clearing, and inspect a narrow player so text does not obscure the work being assessed.

Confirm the required tool-use declaration, file versions and submission receipt through the institution’s process. If a correction is needed after submission, follow its replacement rules; do not silently change the linked video or captions. Polyglot cannot verify authorship, decide whether a tool is permitted or guarantee that an assignment will be accepted.
