Struct SpeechItem

pub struct SpeechItem {
    pub audio_samples: Vec<f32>,
    pub sample_rate: usize,
    pub label: SpeechCommandClass,
}

Speech item with audio samples and label.

The audio samples are floats in the range [-1.0, 1.0]. The sample rate is in Hz. The label is the class index (see SpeechCommandClass). To convert to usize simply use as usize. To convert label to string use .to_string().

The original label is also stored in the label_original field for debugging and remapping if needed.

Fields

audio_samples: Vec<f32>

Audio samples in the range [-1.0, 1.0].

sample_rate: usize

The sample rate of the audio.

label: SpeechCommandClass

The label of the audio.
