The Generative Face Description (PAF‑GFD) AIM produces the Face Descriptors of a machine-generated face from the Text and the Machine Speech the face utters. When a Face Personal Status is supplied, the face expresses it; when it is absent, the face carries visemes with a neutral expression:
| Receives | Text Object | The Text the face utters. |
| Machine Speech | The Speech the face utters, to which the visemes are synchronised. | |
| Face Personal Status | The Personal Status the face expresses (optional). | |
| Produces | Face Descriptors | The Face Descriptors of the machine-generated face. |

8 Conformance Testing
Table 2 provides the Conformance Testing Method for the PAF‑GFD AIM.
If a schema contains references to other schemas, conformance of data for the primary schema implies that any data referencing a secondary schema shall also validate against the relevant schema, if present, and conform with the Qualifier, if present.
| Receives | Text Object | Shall validate against Basic Text Object schema. |
| Machine Speech | Shall validate against Basic Speech Object schema. | |
| Face Personal Status | Shall validate against Personal Status schema. | |
| Produces | Face Descriptors | Shall validate against Face Descriptors Object schema. |
