A voice assistant,
from the board up.

Raspberry Pi voice assistant

Template content: all bracketed text needs your input. Diagrams are illustrative; replace them with real project evidence.

The problem

[What should the assistant do, for whom, and under what constraints? Explain the motivation without assuming the reader knows the project.]

The system

[Replace the diagram below with the real architecture. Identify what runs locally, what uses a service, and what happens if that service is unavailable.]

Microphone → Processing → Response

Illustrative flow only; document the actual system.

What I built

[Describe your own contribution. Link to relevant source files or a specific commit. Separate your implementation from libraries and collaborators’ work.]

A decision worth explaining

[Compare two approaches you considered: recognition, audio capture, latency, privacy, or deployment. State what you selected and why.]

Testing & evidence

[Add your test setup, number of trials, hardware, and observed results. Include failures and limitations. Do not publish invented accuracy or latency figures.]

What I would change next

[Describe the most useful next improvement and the evidence that makes it a priority.]
