source

class espnet2.spk.encoder.identity_encoder.IdentityEncoder(input_size: int)

Bases: AbsEncoder

Identity encoder. Does nothing, just passes frontend feature to the pooling.

Expected to be used for cases when frontend already has a good representation (e.g., SSL features).

• Parameters:input_size – input feature dimension.

Initializes internal Module state, shared by both nn.Module and ScriptModule.

forward(x: Tensor)

Defines the computation performed at every call.

Should be overridden by all subclasses.

NOTE

Although the recipe for forward pass needs to be defined within this function, one should call the Module instance afterwards instead of this since the former takes care of running the registered hooks while the latter silently ignores them.
