Voice & Audio Systems
Capture, codecs, streaming, speech recognition, synthesis, turn detection, noise handling, latency, and conversational UX.
Mental model
Voice systems are real-time pipelines. Audio framing, endpointing, ASR, reasoning, TTS, interruption, and playback each consume the latency budget.
How to study Voice & Audio Systems
Begin by restating the mental model in your own words, then connect it to a concrete system you have built or operated. Name the mechanism, the constraint it addresses, and the trade-off it introduces. Use Web Audio API to check details, but close the source before writing your explanation. Retrieval is the learning step; rereading is only preparation.
Next, compare Voice & Audio Systems with Vision Models, Pose & Motion Tracking. Ask what changes in correctness, latency, resource use, operability, and failure recovery. Complete Design exercise: Voice & Audio Systems and preserve the command, input, output, and one failed attempt as evidence. Finish by explaining the idea without jargon to someone who has not studied the track.
Proof of understanding
- Explain the mechanism from first principles and identify the state it reads or changes.
- Give one situation where the concept is the right choice and one where it is not.
- Predict a realistic failure mode before running the drill, then compare the prediction with evidence.
- Connect the result to a roadmap or build artifact instead of treating the concept as isolated trivia.

Design exercise: Voice & Audio Systems
Capture, codecs, streaming, speech recognition, synthesis, turn detection, noise handling, latency, and conversational UX. Implement designOutline() returning non-empty values for: audioPipeline, turnDetection, latencyBudget. Each value must name a concrete mechanism or decision.
Expected evidence: A design outline with audioPipeline, turnDetection, latencyBudget plus an explicit failure mode or trade-off.

- What is endpointing, and why does it dominate perceived latency in a voice agent?

Synthesize: AI Models & Training
Move from transformer foundations through pre-training, fine-tuning, post-training, compression, and evaluation. Produce one working system, benchmark, or evidence-backed design that integrates the path.
- Implements or precisely models the core mechanisms from all three milestones
- Includes at least one injected failure or adversarial case and demonstrates recovery
- Reports quality, latency, resource, reliability, or usability measurements relevant to the domain
- Ships a concise architecture note explaining decisions, trade-offs, and remaining risks
