Struct VadConfig 

pub struct VadConfig {
    pub enabled: bool,
    pub sensitivity: f32,
    pub padding_chunks: u32,
    pub min_speech_duration_ms: u32,
}

Local Voice Activity Detection configuration.

This struct defines parameters for local VAD processing, including sensitivity, audio chunking, and speech segment filtering. Adjust these fields to control how strictly speech is detected and how short segments are filtered out.

Fields

• enabled: Whether local VAD is enabled
• sensitivity: Speech detection sensitivity (0.0-1.0). Lower values are stricter and less likely to classify audio as speech.
• padding_chunks: Number of non-speech chunks to include before and after detected speech
• min_speech_duration_ms: Minimum duration (ms) for a segment to be considered valid speech

Examples

use subx_cli::config::VadConfig;

let vad = VadConfig::default();
assert!(vad.enabled);
assert_eq!(vad.sensitivity, 0.25);

Fields

enabled: bool

Whether to enable local VAD method.

sensitivity: f32

Speech detection sensitivity (0.0-1.0).

Lower values are stricter: a smaller value means the detector is less likely to classify a chunk as speech. For example, 0.25 is more strict than 0.75.

padding_chunks: u32

Number of non-speech chunks to pad before and after detected speech.

min_speech_duration_ms: u32

Minimum speech duration in milliseconds.

Segments shorter than this value will be discarded as noise or non-speech.

Implementations

impl VadConfig

pub fn validate(&self) -> Result<()>

Validate the local VAD configuration for correctness.

Ensures that all VAD-related parameters are within acceptable ranges and have valid values for audio processing.

Returns

Returns Ok(()) if validation passes, or an error describing the validation failure.

Errors

This function returns an error if:

• sensitivity is outside the valid range (0.0-1.0)
