    Computes the STOI (See [1][2]) of a denoised signal compared to a clean
    signal, The output is expected to have a monotonic relation with the
    subjective speech-intelligibility, where a higher score denotes better
    speech intelligibility. Uses pystoi under the hood.

    Parameters
    ----------
    estimates : AudioSignal
        Denoised speech
    references : AudioSignal
        Clean original speech
    extended : int, optional
        Boolean, whether to use the extended STOI described in [3], by default False

    Returns
    -------
    Tensor[float]
        Short time objective intelligibility measure between clean and
        denoised speech
