The Brief
What you'll do, and what you'll demonstrate.
Pick the best TTS vendor for Spanish children's storytelling on quality, cost, and latency with a defensible methodology.
This is not a research exercise. It is the work a researcher does to produce findings that withstand scrutiny. That distinction matters to every hiring manager who has seen candidates summarize papers and none who have produced original findings under expert review.
When you finish, you will have something most graduates do not: a real-world deliverable, verified by Ewance, that you can show to a hiring manager and say "I did this. Here is the proof."
Earning criteria — what you'll demonstrate
- Design a listening study that surfaces real perceptual differences
- Compute MOS with honest confidence intervals on small samples
- Combine quality, cost, and latency into a defensible vendor pick
- Translate qualitative perceptual results into a product decision
