class WhisperForCTC extends AnnotatorModel[WhisperForCTC] with HasBatchedAnnotateAudio[WhisperForCTC] with HasAudioFeatureProperties with WriteTensorflowModel with WriteOpenvinoModel with WriteOnnxModel with HasEngine with HasGeneratorProperties with HasProtectedParams

Whisper Model with a language modeling head on top for Connectionist Temporal Classification (CTC).

Whisper is an automatic speech recognition (ASR) system trained on 680,000 hours of multilingual and multitask supervised data collected from the web. It transcribe in multiple languages, as well as translate from those languages into English.

The audio needs to be provided pre-processed an array of floats.

For multilingual models, the language and the task (transcribe or translate) can be set with setLanguage and setTask.

Note that at the moment, this annotator only supports greedy search and only Spark Versions 3.4 and up are supported.

Pretrained models can be loaded with pretrained of the companion object:

val speechToText = WhisperForCTC.pretrained()
  .setInputCols("audio_assembler")
  .setOutputCol("text")

The default model is "asr_whisper_tiny_opt", if no name is provided.

For available pretrained models please see the Models Hub.

To see which models are compatible and how to import them see https://github.com/JohnSnowLabs/spark-nlp/discussions/5669 and to see more extended examples, see WhisperForCTCTestSpec.

Robust Speech Recognition via Large-Scale Weak Supervision

Paper Abstract:

We study the capabilities of speech processing systems trained simply to predict large amounts of transcripts of audio on the internet. When scaled to 680,000 hours of multilingual and multitask supervision, the resulting models generalize well to standard benchmarks and are often competitive with prior fully supervised results but in a zero- shot transfer setting without the need for any fine- tuning. When compared to humans, the models approach their accuracy and robustness. We are releasing models and inference code to serve as a foundation for further work on robust speech processing.

Example

import spark.implicits._
import com.johnsnowlabs.nlp.base._
import com.johnsnowlabs.nlp.annotators._
import com.johnsnowlabs.nlp.annotators.audio.WhisperForCTC
import org.apache.spark.ml.Pipeline

val audioAssembler: AudioAssembler = new AudioAssembler()
  .setInputCol("audio_content")
  .setOutputCol("audio_assembler")

val speechToText: WhisperForCTC = WhisperForCTC
  .pretrained()
  .setInputCols("audio_assembler")
  .setOutputCol("text")

val pipeline: Pipeline = new Pipeline().setStages(Array(audioAssembler, speechToText))

val bufferedSource =
  scala.io.Source.fromFile("src/test/resources/audio/txt/librispeech_asr_0.txt")

val rawFloats = bufferedSource
  .getLines()
  .map(_.split(",").head.trim.toFloat)
  .toArray
bufferedSource.close

val processedAudioFloats = Seq(rawFloats).toDF("audio_content")

val result = pipeline.fit(processedAudioFloats).transform(processedAudioFloats)
result.select("text.result").show(truncate = false)
