Push a stream of air from your throat through your open mouth. No tongue or lip contact.

Americans pronounce homicide as HAH-muh-sahyd (/ˈhɑməˌsaɪd/). Stress falls on the first syllable — keep everything else short and quick. You'll hear it in sentences like "He works as a detective in the homicide division".
Record yourself saying "homicide" and play it back. The mic stays on your device — nothing's uploaded.

Push a stream of air from your throat through your open mouth. No tongue or lip contact.

Relax your lips and drop your jaw significantly. The tongue tip lightly touches behind the bottom front teeth and the back part of the tongue presses down a little to create more dark space in the back of the mouth.

Place your tongue tip near the roof of your mouth behind your top teeth. Push air through the narrow gap. No voicing.

Start with your jaw open wide and your tongue resting low and flat. Glide the front of your tongue up toward the roof of your mouth as your jaw closes halfway.
Touch the tip of your tongue to the roof of your mouth just behind your teeth. Add vocal cord vibration as you release.

The textbook way isn't wrong — it's just not how anyone actually says it.
Stress falls on the first syllable, not the others. Stretch HAH — keep everything else short and quick.
Don't pronounce the first syllable too fully. The unstressed syllable reduces to a schwa — the lazy "uh" sound — in casual speech.
