Add Kokoro v1.0 em_santa voice - #3928
Conversation
📝 WalkthroughWalkthroughThe Kokoro v1.0 voice generator now creates a 54-voice table, validates style tensors, and atomically replaces ChangesKokoro voice table
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The new voice mapping and validation are bounded, but concurrent generator runs can interfere through the shared temporary file and produce a failed or invalid voice artifact. Use a unique temporary path before merging unless concurrent invocation is explicitly excluded. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Use a unique temporary path for each invocation.
If two processes run this script in the same directory, the fixed .voices.bin.tmp path can be truncated, removed by the other process, or renamed while still in use. The current Kokoro workflow runs matrix jobs on separate runners, but manual or reused-workspace invocations can still overlap. Use tempfile.NamedTemporaryFile(delete=False, dir=output_path.parent) or tempfile.mkstemp(), and remove only that invocation's path.

The voice generator now includes em_santa as speaker ID 53 while preserving all existing IDs. It also validates the expected style embedding shape and float32 dtype before generating voices.bin. Metadata generation automatically reflects the expanded 54-voice catalog.
