Qwen3 Forced Aligner Config

The Qwen3 Forced Aligner Config node is a helper node used to initialize the Qwen3-ForcedAligner-0.6B model. This configuration is required if you want the Qwen3 ASR Transcriber to output word-level timestamps.

Parameters

• model_name: The directory name of the Forced Aligner model located in models/diffusion_models/Qwen3-ASR/.
• device: The hardware device to run the aligner on. This should generally match the device used by the Transcriber node.
• precision: The floating-point precision for the aligner model.
• flash_attention_2: Enable Flash Attention 2 for the aligner model to improve performance and reduce memory footprint.

Outputs

• aligner_config: A configuration object that bundles the model path and loading arguments. Connect this to the forced_aligner input of the Qwen3 ASR Transcriber.

Why use this?

Standard ASR models generate text but often lack precise timing for when each word was spoken. The Forced Aligner is a specialized model that takes the generated text and the original audio to “align” them, providing highly accurate start and end times for every word.

Requirements

Ensure you have downloaded the Qwen3-ForcedAligner-0.6B model into your models/diffusion_models/Qwen3-ASR/ folder.
