In our paper "Sound to meaning mappings in the Bouba-Kiki effect." we've created hundreds of nonsense words with the aim of determining how the various phonemes contribute to attributed meanings (related to object shape). In our paper we reference several other works that take a similar approach- working to isolate/characterize how various phonemes are related to meanings. See the reference section of our paper for the unabridged list of suggested reads. Specific reads I would recommend 1) Nielsen, A., & Rendall, D. (2011). The sound of round: evaluating the sound-symbolic role of consonants in the classic Takete-Maluma phenomenon. 2) Magnus (2001) What's in a Word? Studies in Phonosemantics 3) Fort, Martin and Peperkamp (2014) Consonants are More Important than Vowels in the Bouba-kiki Effect

Most of these papers focus on a specific sound-to-meaning mapping (e.g. the mapping of speech sounds to object shape)

The thesis by Magnus takes a more comprehensive look at how sounds in English are mapped to a variety of meanings.

while mapping meaning to a word, the conceptual thought of Indians is completely different from Your Western thought. It made very clear related to phonemes or phonological features of English sounds. when it comes to the concepts of Specific-Sound-Meaning map, the thoughts are completely different. in this connection, I suggest the research scholars to go through the Word and Meaning of Sri Aurabindo and his "The Future Poetry" which will help one way of other to the proposed paper for comparative study.

In The Sounds of the World's Languages, Ladefoged and Maddieson mention some uses of the bilabial trill in different languages.

I can recommend Carol Bellard-Thomson's 'The Literary Stylistics of French' (Manchester University Press, 1992), which has clear examples of the relationships betwen articulation and sound symbolism in that language, much of which also applies to English and other languages. I can't speak for non-European languages, but I would guess that in most languages a frontal sound produced with the tongue high and a very narrow buccal aperture (e.g. i, t) would be used to represent something small and light , whereas a back sound with the tongue low and the buccal aperture much wider (e.g. a, d) would be used to represent something heavy.
