text_transformer

Stateless text transformation processor for Pipecat.

class pipecat.processors.text_transformer.StatelessTextTransformer(transform_fn: Callable[[str], str] | Callable[[str], Coroutine[None, None, str]])

Bases: FrameProcessor

Processor that applies transformation functions to text frames.

This processor intercepts TextFrame objects and applies a user-provided transformation function to the text content. The function can be either synchronous or asynchronous (coroutine).

__init__(transform_fn: Callable[[str], str] | Callable[[str], Coroutine[None, None, str]])

Initialize the text transformer.

Parameters:

transform_fn – Function to apply to text content. Can be synchronous (str -> str) or asynchronous (str -> Coroutine[None, None, str]).

async process_frame(frame: Frame, direction: FrameDirection)

Process frames, applying transformation to text frames.

Parameters:

• frame – The frame to process.

• direction – The direction of frame flow in the pipeline.
