Functions

DS_AddHotWord^⚠

@brief Add a hot-word and its boost.

DS_ClearHotWords^⚠

@brief Removes all elements from the hot-words map.

DS_CreateModel^⚠

@brief An object providing an interface to a trained DeepSpeech model.

DS_CreateStream^⚠

@brief Create a new streaming inference state. The streaming state returned by this function can then be passed to {@link DS_FeedAudioContent()} and {@link DS_FinishStream()}.

DS_DisableExternalScorer^⚠

@brief Disable decoding using an external scorer.

DS_EnableExternalScorer^⚠

@brief Enable decoding using an external scorer.

DS_EraseHotWord^⚠

@brief Remove entry for a hot-word from the hot-words map.

DS_ErrorCodeToErrorMessage^⚠

@brief Returns a textual description corresponding to an error code. The string returned must be freed with @{link DS_FreeString()}.

DS_FeedAudioContent^⚠

@brief Feed audio samples to an ongoing streaming inference.

DS_FinishStream^⚠

@brief Compute the final decoding of an ongoing streaming inference and return the result. Signals the end of an ongoing streaming inference.

DS_FinishStreamWithMetadata^⚠

@brief Compute the final decoding of an ongoing streaming inference and return results including metadata. Signals the end of an ongoing streaming inference.

DS_FreeMetadata^⚠

@brief Free memory allocated for metadata information.

DS_FreeModel^⚠

@brief Frees associated resources and destroys model object.

DS_FreeStream^⚠

@brief Destroy a streaming state without decoding the computed logits. This can be used if you no longer need the result of an ongoing streaming inference and don’t want to perform a costly decode operation.

DS_FreeString^⚠

@brief Free a char* string returned by the DeepSpeech API.

DS_GetModelBeamWidth^⚠

@brief Get beam width value used by the model. If {@link DS_SetModelBeamWidth} was not called before, will return the default value loaded from the model file.

DS_GetModelSampleRate^⚠

@brief Return the sample rate expected by a model.

DS_IntermediateDecode^⚠

@brief Compute the intermediate decoding of an ongoing streaming inference.

DS_IntermediateDecodeWithMetadata^⚠

@brief Compute the intermediate decoding of an ongoing streaming inference, return results including metadata.

DS_SetModelBeamWidth^⚠

@brief Set beam width value used by the model.

DS_SetScorerAlphaBeta^⚠

@brief Set hyperparameters alpha and beta of the external scorer.

DS_SpeechToText^⚠

@brief Use the DeepSpeech model to convert speech to text.

DS_SpeechToTextWithMetadata^⚠

@brief Use the DeepSpeech model to convert speech to text and output results including metadata.

DS_Version^⚠

@brief Returns the version of this library. The returned version is a semantic version (SemVer 2.0.0). The string returned must be freed with {@link DS_FreeString()}.
