Actual values of shimmer, intensity, pitch and jitter independently assessed by a senior speech and language therapist

No.	Sex	Age	Type of rehab.	Pitch (Hz)	Intensity (dB)	Jitter (%)	Shimmer (%)	SLT’s comments
1	M	23	Primary TEP	143.0	70.3	3.5	19.8
2.	M	50	Secondary TEP	140.9	50	3.7	18.1	Intensity is less compared to others
3.	M	38	Secondary TEP	194.3	67.4	4.6	21.4
4.	M	72	Primary TEP	147.5	70.8	2.6	17.8
5.	M	78	Electro larynx	256.7	72.8	4.2	19.6	Worst voice. Pitch, jitter and shimmer are very high
6.	F	55	NTL	242.8	70.5	3.4	18.0	May be this is one of the best voice in terms of pitch and intensity. However jitter and shimmer values are a little high
7.	M	61	Electro larynx	115.3	69.3	1.7	14.4
8.	M	61	Electro larynx	94.0	68.3	1.4	13.9
9.	F	45	Primary TEP	381.9	60.7	6.8	21.2
10.	M	44	Secondary TEP	126.4	71.8	3.3	17.9
11.	M	72	Primary TEP	178.9	65.5	2.2	17.2
12.	M	55	NTL	185.7	70.1	3.0	18.8
13.	M	61	Primary TEP	99.4	74.1	0.7	9.7
14.	M	45	Secondary TEP	156.2	68.9	4.8	21.4
15.	M	52	Oesophageal speech	212.6	69.2	3.8	20.0	Poor voice. High pitch and low intensity
16.	M	38	Electrolarynx	103.0	72.2	1.3	8.2
17.	M	52	Secondary TEP	118.9	72.4	3.8	13.3
18.	M	60	Primary TEP	152.9	68.6	3.1	18.5
19.	M	58	Primary TEP	182.2	78.8	2.9	17.3
20.	M	70	Secondary TEP	439.6	74.8	5.9	20.8	High variation in pitch from one sample to another. Probably because of the noisy environment
21.	M	70	Secondary TEP	189.9	83.9	5.2	22.2
22.	M	70	Secondary TEP	124.6	84.1	3.5	33.1
23.	M	65	NTLP	183.3	77.0	5.0	22.8
24.	M	65	NTLP	102.2	91.2	5.3	15.4	May be this is one of the best voice in terms of pitch and intensity. However jitter and shimmer values are little high
