I think you mean passive voice! because only in passive we have an emphasis on the object. However, if the subject was an object or a thing, it doesn't necessairly mean that the sentence is in passive voice.
for example: the lake shimmered
the car backfired
the computer is processing the data.
the earthquake destroyed many houses
so, here the sentences are not in passive though the subject is an inanimate or an object coz u still can turn them into passive like:
The data is being processed
many houses were destroyed
I hope this could help...
