| # Cadence compact cascade v0.1 protocol |
|
|
| This protocol fixes the release-candidate composition and acceptance checks |
| before the integrated candidate is scored. Its purpose is to replace repeated |
| shared-encoder fine-tuning with independently gated acoustic components. |
|
|
| ## Fixed composition |
|
|
| - Cadence affect-focus v0.9 remains the 241,904,650-parameter ONNX graph. |
| - The frozen base-ASR view supplies CTC transcription and a padding-safe |
| 5,120-value probe embedding in one encoder pass. |
| - A VocalSound linear head may add `laugh`, `sigh`, `cough`, `throat_clear`, or |
| `sneeze` at utterance scope. |
| - Styles are disabled in v0.1. A BERSt binary shouting head was evaluated but |
| missed the predeclared development gate (F1 0.689, recall 0.551) at the |
| required ordinary-speech false-positive limits. `whispering` is also disabled |
| until a speech-specific head passes an equivalent protocol. |
| - The event head uses a trained `none` logit and abstains unless its validation-set |
| margin threshold is met. Raw SenseVoice AED and emotion tags are excluded. |
| - Existing joint event-presence and style allowlists remain empty. The retained |
| v0.9 localized-event branch remains limited to `laugh`, `cough`, and |
| `throat_clear` at confidence 0.98 or above. |
| - emotion2vec+ remains an evaluation and teacher baseline. It is not part of |
| the compact deployment model. |
|
|
| The linear event head adds fewer than 31,000 parameters. The unique deployment |
| parameter count therefore remains below 242 million. The NumPy head artifact |
| do not require PyTorch at inference time. |
|
|
| ## Opened development checks |
|
|
| The existing VocalSound inspection partition and BERSt development partition |
| are opened benchmarks, |
| not sealed gold data. They may determine whether a head is worth carrying into |
| the release candidate, but they cannot support a final generalization claim. |
|
|
| The VocalSound head must reach macro-F1 of at least 0.80. The BERSt head must |
| reach shouting F1 of at least 0.85 with precision and recall of at least 0.80, |
| and a false-positive rate no greater than 0.05 on BERSt ordinary speech. It |
| must emit no style on the external ordinary-speech controls. A head that misses |
| its gate is omitted rather than compensated for by lowering a threshold. |
|
|
| The discarded FSD50K head is not a release component. It reached 0.735 macro-F1 |
| on its opened sound-event inspection set but falsely labelled all four ordinary |
| hostile-lexical speech controls as `whispering`. This is recorded as a rejected |
| experiment, not repaired by changing its threshold. |
|
|
| ## Integration checks |
|
|
| The candidate must satisfy all of the following: |
|
|
| 1. The exported ONNX probe embedding matches the frozen training representation |
| within a maximum absolute error of 0.0005 on at least 20 clips. |
| 2. Each enabled head has a false-positive clip rate no greater than 0.05 on |
| speech controls outside its source domain. |
| 3. The four neutral hostile-lexical controls produce an exact normalized |
| transcript, no event or style output, and affect abstention. |
| 4. JSON schema validation, deterministic XML, batch API, and pseudo-streaming |
| smoke checks pass. |
| 5. INT8 is evaluated only after the full-precision candidate passes these |
| checks. Probe decisions must agree between full precision and INT8 on the |
| release regression suite. |
|
|
| The earlier affect cross-corpus blocker and the required fresh consented human |
| hostile-speech recording remain independent release gates. Passing this |
| protocol produces a private release candidate, not permission for a public |
| weight release. |
