OK, so here's a new thread for everyone to post their custom sound alerts.

Sound alerts vary from language to language due to the words saved in the csf voice file

Using the V32 OS disc, I have created the following phrases.

gb_f.csf
323 322 323 88 237 296 229 285
hibeep-lobeep-hibeep pause caution danger in_front_of_you do_not_overtake

us_f.csf
463 464 463 112 379 260
hibeep-lobeep-hibeep pause caution ahead

463 464 463 112 379 372
hibeep-lobeep-hibeep pause caution in_front_of_you

d_f.csf
437 438 437 127 350 354 335
hibeep-lobeep-hibeep pause Achtung Gefahr vor_Ihnen
