Introduction Based on data from 243 tone systems and 74 vowel Methodology systems, we argue that Africa as a whole does not form a The ALFA Project unified linguistic area Tone database Results Likewise, these data do not provide evidence for the Tone Vowel systems Macro-Sudan Belt as a unified phonological area Conclusion Instead, we find evidence for smaller linguistic micro-areas References South of Lake Chad The Nigeria/Cameroon border The Ghana/Togo/Burkina Faso cluster The Kru/Mande Zone Overview Areal features Hyman et al. 1 Introduction Introduction Methodology The ALFA Project 2 Methodology Tone database The ALFA Project Results Tone Tone database Vowel systems Conclusion References 3 Results Tone Vowel systems 4 Conclusion Areal Linguistic Features of Africa (ALFA) Project Areal features The ALFA Project is the work of 11 linguists at UC Hyman et al. Berkeley Introduction We are gathering data on 7 linguistic features that have Methodology The ALFA been claimed to be \African" Project Tone database Tone Results ATR systems Tone Vowel systems Nasal vowels Conclusion Syllable and word structure References Verb extensions Serial verbs S AUX O V For each feature, we have created a database of languages coded for key properties We created a web application to map the languages based on these properties to identify areal and genetic patterns Language mapper Areal features Hyman et al. Introduction Methodology The ALFA Project Language mapper (Ewert, 2015) is a web application Tone database Results Input: spreadsheets of data, Glottolog language data Tone (Hammarstr¨omet al., 2015) Vowel systems Output: a Google map of language data letter-coded with Conclusion genetic information and color-coded for linguistic features References (Google, 2015) Tone database Areal features Hyman et al. Introduction We gathered tone data from a database of 662 tone Methodology languages (Hyman, 2015) The ALFA Project 243 African languages Tone database Results The data was recoded with a numerical system we Tone designed to encode equivalencies across different traditions Vowel systems Conclusion of representation References Our coding allowed us to look at numerous features of tone inventories including: Number and identity of level tones Number and identity of downstepped tones Number, direction, and identity of contour tones African languages by number of surface level tones Areal features Hyman et al. Introduction Languages were coded by the number of non-contour Methodology tones in their surface tone inventories The ALFA Project Tone database This count included downstepped tones as constituting a Results separate surface level Tone Vowel systems The goal of this analysis was to separate languages based Conclusion on the number of contrastive pitch levels they distinguish References on the surface There are several micro-areas defined by the number of levels that languages distinguish in their surface tone inventories Number of surface level tones Areal features Hyman et al. Introduction Methodology The ALFA Project Tone database Results Tone Vowel systems Conclusion References Number of surface level tones - Mande/Kru Zone Areal features Hyman et al. Introduction Methodology The ALFA Project Tone database Results Tone Vowel systems Conclusion References Number of surface level tones - Nigeria/Cameroon vs. Southern Bantu Areal features Hyman et al. Introduction Methodology The ALFA Project Tone database Results Tone Vowel systems Conclusion References Number of surface level tones - Summary Areal features Hyman et al. Introduction Methodology The ALFA Mande languages near Kru have more surface levels Project Tone database Bantoid languages near the Nigeria/Cameroon border Results Tone have more levels that Bantu languages in southern Africa Vowel systems There are three areas of three level tones Conclusion Ghana/Togo/Burkina Faso References South of Lake Chad Ethiopia/Sudan African languages with three surface level tones Areal features Hyman et al. As seen in the previous maps of number of surface level Introduction tones across African languages, the most common number Methodology The ALFA of levels is 3, especially in the Macro-Sudan belt. Project Tone database The following maps show only those African languages Results which have exactly three level tones, differentiating them Tone Vowel systems by which tones are in their inventories: Conclusion Low, Mid, High References Low, !High, High Low, !Low, High Low, High, Superhigh We recognize that which three levels a given language has is often a matter of analysis. Three surface level tones Areal features Hyman et al. Introduction Methodology The ALFA Project Tone database Results Tone Vowel systems Conclusion References Three surface level tones - West Africa Areal features Hyman et al. Introduction Methodology The ALFA Project Tone database Results Tone Vowel systems Conclusion References Three surface level tones - Summary Areal features Hyman et al. Introduction Methodology The ALFA Project Tone database Languages in Southern Africa have downstep. Results Tone Bantoid languages nearer the Nigeria/Cameroon border Vowel systems are more likely to have a mid tone. Conclusion References Languages south of Lake Chad have a mid tone. African languages by number of surface contour tones Areal features Hyman et al. Introduction Methodology The ALFA Project We have seen the distribution of surface level tones, and Tone database now we turn to surface contours. Results Tone We find that high numbers of contour tones are found in Vowel systems Conclusion the Kru/Mande zone of southern West Africa. References There are also marked areas that lack contour tones entirely. Number of surface contour tones Areal features Hyman et al.

Introduction Methodology The ALFA Project Tone database Results Tone Vowel systems Conclusion References Number of surface contour tones - Summary Areal features Hyman et al. There is a high concentration of numerous contour tones Introduction in the Kru/Mande-zone, but not in Mande languages Methodology The ALFA further away. Project Tone database There are sporadic languages with high numbers of Results Tone contours throughout the rest of the Macro-Sudan belt (cf. Vowel systems Central Sudanic). Conclusion References Bantoid languages on the Nigeria/Cameroon border tend to have more contours than Bantu languages in southern Africa There are two regions that lack contour tones entirely Ghana/Togo/Burkina Faso South of Lake Chad Are languages with a high number of level tones more likely to have a high number of contours? Areal features Hyman et al. Introduction Methodology The ALFA Project The Ghana/Togo/Burkina Faso cluster is an area of Tone database 3-level tones that lacks contours Results Tone Central Sudanic languages have 3 level tones and most Vowel systems Conclusion have no contours References The Kru/Mande zone has high numbers of level tones and contours African languages by direction of contour tones Areal features Hyman et al. Introduction Methodology The ALFA Project Tone database Here we are interested whether falling versus rising Results contour tones pattern together areally. Tone Vowel systems We find little evidence that the direction of contours is an Conclusion areal feature; however, the Kru/Mande zone is the only References area where multiple languages show complex contours.
