Table 6. Mean error rates using a classification technique based on the majority of nasal/non-nasal frames for each zone.

	Part of the zone considered
EMG Channel	[0–100%]	[0%-50%]	[25%-75%]	[50%-100%]
1	25.2%	28.0%	24.3%	27.7%
2	21.5%	25.2%	28.7%	32.2%
3	25.7%	27.1%	28.7%	33.7%
4	24.3%	22.9%	23.3%	31.7%
5	32.2%	29.0%	30.7%	36.1%
Mean	25.8%	26.5%	27.1%	32.3%

Each column of the table shows which part of the zone is being considered, where 0% represents the zone start and 100% the zone end (e.g. in 50%-100% interval only the samples in the last half of each zone are being considered).
