Martha Speaks

It revolves around a talking dog named Martha (voiced by Tabitha St. Germain), who is owned by 10-year-old Helen Lorraine (known in the books as Helen Finney). Whenever Helen feeds Martha alphabet soup, the noodle letters somehow travel to her brain instead of her stomach, giving her the ability to speak human words. The show focuses on mainly synonyms and vocabulary, with each episode featuring an underlying theme illustrated with (usually informal) keywords, but can occasionally focus on introducing preschoolers to various science and other learning concepts, such as the Spanish language through passing mentions, history, and astronomy. The show takes place in the fictional town of Wagstaff City, likely referring to Flagstaff, Arizona.
