Ther ar, in fakt, t[úe] branchez, or at [w]l events, t[úe] kweit disti[n]kt praktikal aplik[e]shonz ov the seiens ov F[o]netiks, hwich for wont ov beter n[e]mz, ei design[e]t az _filolojikal_ and _deialektikal_. Ther iz hwot m[e] b[i] k[w]ld a filolojikal st[u]di ov F[o]netiks, hwich iz an esenshal part ov the Seiens ov La[n]gwej, and haz for its objekt tu giv a kl[i]r eid[i]a ov the alfabet, not az riten, b[u]t az sp[o]ken. It tr[i]ts ov the mat[i]rialz out ov hwich, the instruments with hwich, and the proses bei hwich, vouelz and konsonants ar formd; and after ekspl[e]ni[n] hou serten leterz agr[i], and difer, in th[e]r mat[i]rial, in the instruments with hwich, and the proses bei hwich th[e] ar prodiúst, it en[e]belz [u]s tu [u]nderstand the k[w]zez and rez[u]lts ov hwot iz k[w]ld F[o]netik Ch[e]nj. In meni respekts the most instr[u]ktiv tr[i]tment ov the jeneral [t][i]ori ov F[o]netiks iz tu b[i] found in the Prâti_s_âkhyas; partikiularli in the [o]ldest (400 B.K.), thát atacht tu the Rig V[e]da.(71) Th[o] the n[u]mber ov posibel soundz m[e] s[i]m infinit the n[u]mber ov r[i]al soundz y[ue]zd in Sanskrit or eni [u]ther given la[n]gwej for the p[u]rpos ov ekspresi[n] diferent sh[e]dz ov m[i]ni[n], iz veri limited. It iz with th[i]z br[w]d kategoriz ov sound al[o]n that the Prâti_s_âkhyas d[i]l; and it iz for a proper [u]nderstandi[n] ov th[i]z the Seiens ov La[n]jgwej haz tu inkl[ue]d within its sf[i]r a k[e]rful st[u]di ov F[o]netiks. The deialektikal st[u]di ov F[o]netiks haz larjer objekts. It wishez tu ekz[w]st [w]l posibel soundz hwich kan b[i] prodiúst bei the v[o]kal organz, litel konsernd az tu hwether th[i]z soundz ok[u]r in eni r[i]al la[n]gwej or not. It iz partikiularli y[ue]sful for the p[u]rpos ov p[e]nti[n], with the [u]tm[o]st akiurasi, the aktiual pron[u]nsi[e]shon ov individiualz, and ov fiksi[n] the f[e]ntest sh[e]dz ov deialektik vareieti. The m[o]st marvel[u]s ach[i]vment in this branch ov apleid f[o]netiks m[e] b[i] s[i]n in Mr. Bell’z “Vizibel Sp[i]ch.” Th[i]z t[úe] branchez ov f[o]netik seiens, houever, shud b[i] kept k[e]rfuli disti[n]kt. Az the found[e]shon ov a praktikal alfabet, leikweiz az the onli s[e]f found[e]shon for the Seiens ov La[n]gwej, w[i] wont filolojikal or [t][i][o]retik F[o]netiks. W[i] wont an [u]nderstandi[n] ov thez jeneral prinsipelz and thez br[w]d kategoriz ov sound hwich ar tr[i]ted in the Prâtisâkhyas; w[i] d[ue] not wont eni ov the miniút deialektikal disti[n]kshonz hwich hav no gramatikal p[u]rpos and ar th[e]rfor outseid the p[e]l ov gramatikal seiens. T[ue], miniút disti[n]kshon prodi[ue]sez konfiu[z]on, and hw[e]r it kan b[i] avoided, without a sakrifeiz ov akiurasi, it [w]t tu b[i] avoided. Hw[e]r v[e]gnes ekzists in r[i]aliti, and hwer n[e]tiur alouz a br[w]d marjin on either seid, it wud b[i] ro[n] tu ignor thát latitiud. Akiurasi itself wud h[i]r bek[u]m inakiurasi.
