Get the signal-to-noise ratio of a recording containing a single utterance and some leading or trailing noise

Description

Get the signal-to-noise ratio of a recording containing a single utterance and some leading or trailing noise

Usage

getSNR(wave, begin, end)

Arguments

wave	Required. Either a tuneR::Wave object or a valid file path to an existing wav file.
begin	Integer. The first sample in the wave to be considered part of the speech signal. If NULL (the default), will use the automatically detected value output by findSpeech(wave).
end	Integer. The last sample in the wave to be considered part of the speech signal. If NULL (the default), will use the automatically detected value output by findSpeech(wave).

Value

The signal-to-noise ratio of the recording in dB.

Examples

data("samp_wav")
fs <- findSpeech(samp_wav)
snr <- getSNR(samp_wav, fs$begin_s, fs$end_s)
snr
