Questions & Answers about Я слышу шаги в коридоре.
Yes. Слышу already tells you the subject is I, because it is the 1st person singular form of слышать.
So Russian can say either:
- Слышу шаги в коридоре.
- Я слышу шаги в коридоре.
Including я is normal and often sounds a little more explicit or neutral. Leaving it out is also natural, especially when the subject is already clear from context.
Russian distinguishes between hearing and listening:
- слышать / слышу = to hear
- слушать / слушаю = to listen
So:
- Я слышу шаги = I hear footsteps
- Я слушаю музыку = I am listening to music
In this sentence, the person is perceiving a sound, not actively trying to listen, so слышу is the correct verb.
