Abstract:
The present study investigates the effect of acute alcohol consumption on speech in Hungarian subjects. The measures used to reveal these effects were tongue-twisters, which were grouped according to their linguistic features. The number and type of speech errors while uttering the tongue-twisters were compared between intoxicated and sober conditions. The results showed that subjects made more speech errors in alcohol influenced than in sober states in all types of the tongue-twisters except for those using foreign words. Changes in the articulation rate, number of pauses and fundamental frequency were investigated as well. In the intoxicated state, no changes were observed in fundamental frequency and articulation rate, while the number of pauses increased.

Catalytic hydrogenation is similar to the reduction of an alkene or alkyne by adding H2 across the pi bond in the presence of transition metal catalysts like Raney Ni, Pd–C, Pt, or Ru. Aldehydes and ketones can be reduced by this method, often under mild to moderate heat...
