  regression_window_length = 0
)

Arguments

Second MFCC object (reference, y-axis)

coefficient_weight

Weight for cepstral coefficients (default: 1.0)

log_energy_weight

Weight for log energy (c0) (default: 0.0)

coefficient_regression_weight

Weight for coefficient regression (default: 0.0)

log_energy_regression_weight

Weight for energy regression (default: 0.0)

regression_window_length

Window for regression calculation (default: 0.0)

Value

A DTW object

Examples

s1 <- Sound$create_tone(frequency = 200, duration = 0.3, sampling_rate =
 16000)
s2 <- Sound$create_tone(frequency = 220, duration = 0.3, sampling_rate =
 16000)
dtw <- mfccs_to_dtw(s1$to_mfcc(), s2$to_mfcc())
