*Component items*:
  * *Speaker sensory data* (*speaker-sensory-data*)
   * Speaker - palatine tonsil receptors (palatine-tonsil-receptors -> [BrainRegionLPC_PN_SG_JUG LPC.PN.SG.JUG]): visceral mucous membrane over soft palate and tonsil
  * *Speaker phonatory muscles* (*speaker-phonatory-muscles*): move vocal cords together and serve production of voice
   * [http://en.wikipedia.org/wiki/Lateral_cricoarytenoid_muscle Speaker - lateral cricoarytenoid muscle] ([BrainRegionLAC_PN_PSYM_ILG LAC.PN.PSYM.ILG] -> [HumanMusclesNeck lateral-cricoarytenoid-muscle]): adduct and medially rotate the cartilage, pulling the vocal ligaments towards the midline and backwards and so closing off the rima glottidis
   * [http://en.wikipedia.org/wiki/Arytenoid_muscle Speaker - arytenoid muscle] ([BrainRegionLPC_HL_AMB LPC.HL.AMB] -> [HumanMusclesNeck arytenoid-muscle]): approximate the arytenoid cartilages (close rima glottidis)
   * [http://en.wikipedia.org/wiki/Cricothyroid_muscle Speaker - cricothyroid muscle] ([BrainRegionLPC_HL_AMB LPC.HL.AMB] -> [HumanMusclesNeck cricothyroid-muscle]): tension and elongation of the vocal folds (has minor adductory effect)
   * [http://en.wikipedia.org/wiki/Thyroarytenoid_muscle Speaker - thyroarytenoid muscle] ([BrainRegionLAC_PN_PSYM_ILG LAC.PN.PSYM.ILG] -> [HumanMusclesNeck thyroarytenoid-muscle]): thickens the vocal folds and decreases length; also helps to adduct the vocal folds during speech
   * [http://en.wikipedia.org/wiki/Oblique_arytenoid Speaker - oblique arytenoid muscle] ([BrainRegionLAC_PN_PSYM_ILG LAC.PN.PSYM.ILG] -> [HumanMusclesNeck oblique-arytenoid-muscle]): sphincter of the laryngeal inlet
   * [http://en.wikipedia.org/wiki/Posterior_cricoarytenoid_muscle Speaker - posterior cricoarytenoid muscle] ([BrainRegionLAC_PN_PSYM_ILG LAC.PN.PSYM.ILG] -> [HumanMusclesNeck posterior-cricoarytenoid-muscle]): abducts and laterally rotates the cartilage, pulling the vocal ligaments away from the midline and forward and so opening the rima glottidis
   * [http://en.wikipedia.org/wiki/Thyroepiglottic_muscle Speaker - thyroepiglottic muscle] ([BrainRegionLAC_PN_PSYM_ILG LAC.PN.PSYM.ILG] -> [HumanMusclesNeck thyroepiglottic-muscle]): closes the inlet to the larynx
   * [http://en.wikipedia.org/wiki/Aryepiglottic_muscle Speaker - aryepiglottic muscle] ([BrainRegionLAC_PN_PSYM_ILG LAC.PN.PSYM.ILG] -> [HumanMusclesNeck aryepiglottic-muscle]): close the inlet
  * *Speaker respiratory larynx muscles* (*speaker-respiratory-muscles*): move vocal cords apart and serve breathing
   * [http://en.wikipedia.org/wiki/Thyrohyoid_muscle Speaker - thyrohyoid muscle] ([BrainRegionLPC_SC_VH_VM LPC.SC.VH.VM] -> [HumanMusclesNeck larynx-thyrohyoid-muscle]): depresses the hyoid and elevates the larynx
   * [http://en.wikipedia.org/wiki/Omohyoid_muscle Speaker - omohyoid muscle] ([BrainRegionLPC_SC_VH_VM LPC.SC.VH.VM] -> [HumanMusclesNeck omohyoid-muscle]): depresses the larynx and hyoid bone; carries hyoid bone backward and to the side
   * [http://en.wikipedia.org/wiki/Palatopharyngeus_muscle Speaker - palatopharyngeus muscle] ([BrainRegionLPC_HL_AMB LPC.HL.AMB] -> [HumanMusclesHead palatopharyngeus-muscle]): pulls pharynx and larynx
   * [http://en.wikipedia.org/wiki/Sternohyoid_muscle Speaker - sternohyoid muscle] ([BrainRegionLPC_SC_VH_VM LPC.SC.VH.VM] -> [HumanMusclesNeck sternohyoid-muscle]): depress hyoid bone
   * [http://en.wikipedia.org/wiki/Sternothyroid_muscle Speaker - sternothyroid muscle] ([BrainRegionLPC_SC_VH_VM LPC.SC.VH.VM] -> [HumanMusclesNeck sternothyroid-muscle]): elevates larynx, may slightly depress hyoid bone
   * [http://en.wikipedia.org/wiki/Levator_muscle_of_thyroid_gland Speaker - levator muscle of thyroid gland] ([BrainRegionLPC_HL_AMB LPC.HL.AMB] -> [HumanMusclesNeck thyroid-gland-levator-muscle]): elevates the thyroid gland
