Extract

Tima (ISO 639-3: tms) is a Niger-Congo language spoken by roughly 7,000 people in the Nuba mountains of Sudan, in north-eastern Africa, as well as in smaller communities in the bigger towns of Sudan such as Khartoum and Port Sudan. It is part of the Katla language group which includes the languages Katla and Julut as well as Tima, with Tima being the most distinct of the three. All three languages are regarded as endangered, mainly due to the spreading influence of Arabic in recent decades, but also due to greater speaker mobility. Broadly speaking, there is a decline in speaker fluency from older to younger speakers of Tima. The Tima people are not only exposed to Arabic as the lingua franca and official language of Sudan, but also to English and Kiswahili. These latter languages were introduced into the school system during the extremely difficult circumstances of the second civil war (1983–2005), when teachers from Kenya came to the Tima region (in addition, many Tima people went to Kenya for further education).1

Figure 2. Burst/aspiration duration for 1315 tokens of the voiced and voiceless plosives and the bilabial implosive of Tima. Data are from word-initial and word-medial position. Numbers in the boxes indicate numbers of tokens.

Figure 3. Mean Strength of Excitation for 672 tokens of the voiced and voiceless plosives and the bilabial implosive of Tima. Data are from word-medial position only. Note that there are only eighteen tokens of /ɓ/ and twelve of /ɟ/. Numbers in the boxes indicate numbers of tokens.

Figure 5. Time waveforms and spectrograms for the words (a) /kúrùh/ push and (b) /kùɽûr/ side arm of the big river as produced by speaker HKD. The red line on the time-waveform shows f0 (range 50–250Hz). The spectrogram shows the range 0–5 kHz. Note that in the phonetic labelling, ‘R’ denotes /ɽ/ and ‘H’ marks aspiration.

Figure 6. Vowel plots showing mean formant values for 2213 tokens (note that 279 tokens with measured F2 higher than 2200Hz, and/or F1 higher than 1000Hz, were removed from the database before plotting). Short and long vowel data are combined. (a) Vowels presented separately for +/–ATR, with 95$\%$ confidence ellipses. (b) Vowels combined on the one plot without ellipses.

Figure 7. Boxplots showing spectral tilt in the frequency range 0.1kHz to 1.0kHz according to +/–ATR (in colour) and according to vowel height (in linetype). 2492 long and short vowel tokens are combined in this plot.

Table 2 Mean, standard deviation and number of tokens for long and short vowel durations in Tima (in milliseconds). The final column gives the ratio of long/short vowel duration.

Figure 9

Figure 8. Boxplots showing f0 (2326 tokens), sampled at the temporal midpoint of the vowel. Long and short vowels are combined, but contour tones are excluded. Data are from three male speakers. F0 values of less than 80Hz and more than 230Hz were removed as outliers. Note that !H denotes ↓H.

Figure 10

Figure 9. GAM-smoothed timeplots showing f0 (2519 tokens). Data are shown separately for short vowels (simple tone); for long vowels (simple tone); and for long vowels with a contour tone. Data are from three male speakers. F0 values of less than 80Hz and more than 230Hz were treated as NA values for the purposes of plotting. Grey bands surrounding the smoothed lines denote confidence intervals. Note that ‘!High’ denotes the downstepped ↓High tone. Note also that in the panel labelled ‘contour’, the light green line denotes a falling contour HL, and the pink line denotes a rising contour LH.
