04. Week 18 — Daily Recall

Use this in the morning before your main study block. Answer aloud first, then verify against 02_explainer.md and 03_study_material.md.

Monday

  1. Why does the “awkward pause” matter more in voice than in text? See 02_explainer.md §1-§2.
  2. Whisper + GPT-4 + ElevenLabs sounds strong. Why can it still fail badly? See 02_explainer.md §2.
  3. Streaming versus batch ASR: what changes for user experience and architecture? See 02_explainer.md §3.

Tuesday

  1. At 16 kHz, how many samples arrive in 20 milliseconds, and why do you care? See 02_explainer.md §3.
  2. VAD versus endpointing: what question does each one answer? See 02_explainer.md §3 and 03_study_material.md §4.
  3. What do word-level timestamps buy you beyond subtitles? See 02_explainer.md §3.

Wednesday

  1. Why is TTFA more important than total synthesis time for voice UX? See 02_explainer.md §4.
  2. Voice cloning sounds impressive. What must be true before you ship it? See 02_explainer.md §4 and §8.
  3. Prosody is not cosmetic. Give one product example where tone changes the outcome. See 02_explainer.md §4.

Thursday

  1. Explain the relay-race pipeline over WebSockets in six lines. See 02_explainer.md §5.
  2. What is barge-in, and what should happen the moment it occurs? See 02_explainer.md §5.
  3. Name the main stages in a voice latency budget and give a healthy p95 range for each. See 02_explainer.md §5 and 03_study_material.md §7.

Friday

  1. Native speech-to-speech model versus cascaded pipeline: when does each win? See 02_explainer.md §6.
  2. What are two honest limitations of current voice systems, especially for accents, languages, or telephony? See 02_explainer.md §8.
  3. Which foundation gap would hurt you most in an interview right now: streaming, WebSockets, latency budgeting, or audio basics? See 02_explainer.md §9.
