8 Conformance Testing
Table 2 provides the Conformance Testing Method for the Text-to-Speech with Descriptors (MMC‑TSD) 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 Text Object schema. Text Data shall conform with Text Qualifier. |
| Speech Descriptors | Shall validate against Speech Descriptors schema. | |
| Produces | Synthesised Speech Object | Shall validate against Speech Object schema. Speech Data shall conform with Speech Qualifier. |
