Bob Corff and Claire Corff


View Bob’s IMDB Link here.

Bob Corff has solidified himself as one of the best dialect coaches for actors, one of the most popular voice coaches for speakers in all fields of work, and one of the most successful vocal coaches for singers at every level. He has developed a successful line of audio courses that help actors learn a dialect, learn to get rid of an accent, learn to sing, and also improve their speaking voice. The list of celebrity clients he has taught ranges from Lenny Kravitz to Gwyneth Paltrow and just about everyone in between. Becoming one of the most successful voice, dialect and speaking coaches in the country wasn’t always his plan, however.

When Bob Corff was born in Reading, Pennsylvania, nobody could have guessed that he would grow up to become the premier voice and dialect coach in Los Angeles. The Corff family had no inherent ties to the entertainment industry, neither acting nor singing. However, the family migrated west and Bob spent much of his childhood in California. It was here that he realized his desire to become an entertainer, and like so many college-age students, he started a rock-and-roll band: “The Purple Gang.” After appearing at the grand opening of a local service station, they were offered a contract with MGM records.

Soon thereafter, Corff wanted to take his singing talent and use it to develop himself into a successful actor. He began to study theater and landed his first acting job as the lead in the Los Angeles production of “Hair” — a role he later played on Broadway. He went on to enjoy a successful acting career that included a starring role in more than 103 episodes of “The Everyday Show” and a contract to Universal Studios for which he played parts in many television shows and movies such as “McMillan & Wife,” “The Bold Ones,” “Houston, We’ve Got a Problem,” and was top starred in the Roger Corman cult classic “Gasss.”

Bob never gave up his love for the stage, nor did he give up his love for singing. He performed roles as both an actor and singer in a number of extremely successful stage productions, including Jesus in “Jesus Christ Superstar” and Danny Zuko in Broadway’s production of “Grease.” One of his fondest memories was working personally with Leonard Bernstein in “Mass,” which was just one of three plays that Bob performed at the prestigious Mark Taper Theatre in Los Angeles, California.

Corff was twelve years into his acting career when a friend asked him to help her learn to sing and he found a new passion: vocal coaching. Despite all his success as an actor and singer, voice coaching was where Bob Corff truly excelled. He had a unique approach to the work and because he knew exactly what it took to be a successful singer and a successful actor, his reputation spread rapidly among actors in Hollywood. He soon developed a reputation as the best voice coach in LA and began working with a list of celebrity clients that includes Sally Field, Elijah Wood, Jennifer Aniston, Antonio Banderas, and even Mariah Carey.

Bob Corff currently teaches private voice lessons out of his studio in Los Angeles, California, and thanks to the advances in technology in recent years, he has developed a system for providing voice and dialect coaching for people outside the Los Angeles area. He often travels to film sets as an on-set voice coach for celebrities and new actors alike. His passion for vocal coaching continues to grow with each passing day and with every new student he helps.

Claire Corff

Claire Corff may have started as an apprentice to world-renowned voice coach Bob Corff, but she quickly developed into a great voice coach in her own right. She has since become the co-founder of Corff Voice Studios as well as the co-author of “Achieving the Standard American Accent” and a number of different accent audio courses. Most of the students she has taught through both private lessons and on-set dialect coaching would not guess that this master dialect coach was actually once so shy that her mother forced her into an acting class just to break out of her shell.

Claire was born the middle child of seven children in Steinbeck Country, to an Evangelical Minister father and a Housewife mother. Her mother enrolled young Claire at the Carmel Conservatory to take dancing and acting classes. She was a natural acting talent and soon began to win numerous acting awards and was later accepted to the prestigious Cal Arts as a theater major. While studying at Cal Arts she guest starred in episodic TV shows, several television pilots, feature films, and booked dozens of commercials.

It was early in her professional acting career that she met the popular voice teacher Bob Corff and her plans quickly changed. Bob’s passion for voice and dialect coaching sparked Claire’s own love for teaching voice lessons and she left her acting career behind to become a Los Angeles based dialect coach. Building on her previous studies of phonetics, years of voice lessons, and having played many roles that required learning a foreign accent, she apprenticed Bob in his teaching for a number of years before she gradually started teaching herself. She is currently teaching private voice lessons at Corff Voice Studios, accent reduction classes at the prestigious Strasberg institute, and continues to work with Bob to develop new audio courses so anyone can learn a new accent.
