    Text-to-audio generation pipeline using any `AutoModelForTextToWaveform` or `AutoModelForTextToSpectrogram`. This
    pipeline generates an audio file from an input text and optional other conditional inputs.

    Example:

    ```python
    >>> from transformers import pipeline

    >>> pipe = pipeline(model="suno/bark-small")
    >>> output = pipe("Hey it's HuggingFace on the phone!")

    >>> audio = output["audio"]
    >>> sampling_rate = output["sampling_rate"]
    ```

    Learn more about the basics of using a pipeline in the [pipeline tutorial](../pipeline_tutorial)

    <Tip>

    You can specify parameters passed to the model by using [`TextToAudioPipeline.__call__.forward_params`] or
    [`TextToAudioPipeline.__call__.generate_kwargs`].

    Example:

    ```python
    >>> from transformers import pipeline

    >>> music_generator = pipeline(task="text-to-audio", model="facebook/musicgen-small", framework="pt")

    >>> # diversify the music generation by adding randomness with a high temperature and set a maximum music length
    >>> generate_kwargs = {
    ...     "do_sample": True,
    ...     "temperature": 0.7,
    ...     "max_new_tokens": 35,
    ... }

    >>> outputs = music_generator("Techno music with high melodic riffs", generate_kwargs=generate_kwargs)
    ```

    </Tip>

    This pipeline can currently be loaded from [`pipeline`] using the following task identifiers: `"text-to-speech"` or
    `"text-to-audio"`.

    See the list of available models on [huggingface.co/models](https://huggingface.co/models?filter=text-to-speech).

        Generates speech/audio from the inputs. See the [`TextToAudioPipeline`] documentation for more information.

        Args:
            text_inputs (`str` or `List[str]`):
                The text(s) to generate.
            forward_params (`dict`, *optional*):
                Parameters passed to the model generation/forward method. `forward_params` are always passed to the
                underlying model.
            generate_kwargs (`dict`, *optional*):
                The dictionary of ad-hoc parametrization of `generate_config` to be used for the generation call. For a
                complete overview of generate, check the [following
                guide](https://huggingface.co/docs/transformers/en/main_classes/text_generation). `generate_kwargs` are
                only passed to the underlying model if the latter is a generative model.

        Return:
            A `dict` or a list of `dict`: The dictionaries have two keys:

            - **audio** (`np.ndarray` of shape `(nb_channels, audio_length)`) -- The generated audio waveform.
            - **sampling_rate** (`int`) -- The sampling rate of the generated audio waveform.
