The present disclosure describes speech or sound-emulating bottle cap apparatuses and systems and methods for manufacture thereof. It will be understood that a bottle cap prohibits gases from escaping a pressurized bottle. Ordinarily, when the cap is removed from the bottle, the escaping gas will emit a sound, but the sound carries no discernable meaning, cognizable message or recognizable sound (aside from gas simply escaping a pressurized container). Embodiments described herein harness gas escaping from a bottle (when the cap is removed) to generate a discernable meaning, cognizable message or otherwise recognizable sound. The sound-chamber may be wrapped or twisted into a coil or helix shape (in addition or as an alternative to miniaturizing it). A coil or helix shape permits recovery of the original sound quality of the initially modeled sound-chamber, resulting in “a sound-emitting cap-chamber” removably or permanently coupled to a bottle cap or bottle as described herein.
