Approved narration and dialogue tracks with authorization and direction notes.
Students cast authorized voices, prepare performable dialogue, direct synthetic delivery, correct pronunciation, and produce organized final audio files.
Section 5: Synthetic Voice and Audio Direction · Lesson 1 of 5 (21 of 45) · 60 minutes · Evidence: Voice casting and authorization record
Close your eyes and imagine your favorite character from any film speaking one sentence. You can probably hear the voice, not just the words. A voice is part of a person: it carries age, place, history and trust. That is exactly why a voice is not free to borrow. Today you learn how to find a voice for your film that you are truly allowed to use, and how to prove it.
Production journal: write your answer below.
What must a filmmaker understand before they can select appropriate authorized voices and document consent source and intended use?
Voice casting means choosing who, or what, will speak each role. For a film with synthetic voices the choice has two halves, and both must pass. The first half is fit: does the voice suit the character’s age, energy, setting and job in the story? The second half is right to use: are you actually allowed to use this voice, for this film, in the way you plan? A voice that fits but fails the second half is not a candidate at all.
Impersonation is making a synthetic voice sound like an identifiable real person: a celebrity, a teacher, a classmate, a politician, a family member. Do not do it, even for a joke, even if you only use a short sample, even if the tool makes it easy. A voice can be cloned from a few seconds of audio, and that is the problem: easy does not mean allowed. Without authorization (the documented permission) there is no permission. Genuine consent is also informed: the person knows what the voice will say, where the film will be shown, and that they can withdraw before release.
Representation is who your casting choices show and how. If every wise elder in your film has one accent and every villain has another, the casting is making a statement you may not intend. Cast for the character, not for a stereotype, and ask whether a different voice would serve the story just as well.
For the short film Last Light, a student needs a voice for Mara, a 34-year-old lighthouse keeper who speaks little and plainly. She auditions three authorized voices. Voice A is warm but sounds like a bedtime story, too soft for a woman who works in storms. Voice B is crisp and clear but sounds as though it belongs to a famous actor; she drops it because it reminds her too closely of a real person. Voice C is low, steady and plain. It comes from the school tool’s library, and its terms allow student film use. She casts Voice C and logs the tool, the voice name, the date she read the terms, and the use: narration and Mara’s dialogue, classroom screening only.
Professional casting directors and independent creators who work with synthetic voices follow a short loop. Watch the steps below as if you were beside a creator choosing a narrator, and pause at each decision to ask who is making the call: the person, or the tool.
The creator starts by writing a character voice brief in plain words: age range, energy, pace, setting. They open the tool’s voice list and listen to a short sample of each candidate using the same test line, because comparing voices on different lines is not a fair comparison. The tool does the speaking. Everything else is judgment: does this voice suit the role, does it sound like a particular real person, and do the terms permit this use?
Careful creators then record their choice before moving on. They note the voice name, where it came from and what the terms said. A hurried creator picks the nicest-sounding voice and finds out later, perhaps at the screening, that it could not be used. Notice also that the tool can describe a voice’s style, but it cannot tell you whether a voice is too close to a real person. That check belongs to you and your teacher.
As you study, record each decision point in your production journal.
| Decision point | What the filmmaker does | What the tool automates | What still needs human review |
|---|---|---|---|
| Define the voice brief | Writes age, energy, pace and setting for each role | Nothing; this is a writing decision | Whether the brief avoids stereotypes about age, gender, region or accent |
| Audition candidates | Plays the same test line through several voices and takes notes | Speaks the test line in each candidate voice | Whether any voice sounds like an identifiable real person |
| Check the right to use | Reads the terms and confirms classroom and film use is allowed | May show a license label or summary | That the summary matches the actual terms, and that the school allows the tool |
| Record the decision | Fills in voice name, source, license or consent, intended use and dates | Nothing | That the record is complete enough for a stranger to verify later |
Studio task: Compare voices for character fit clarity representation and legal use.
Work with a partner. Use the characters from your own film, or Mara and Tomas from Last Light if your film is not ready. Mara is 34, plain-spoken and steady. Tomas is a young supply-boat pilot, quick and friendly.
Coaching tips. Listen on the speakers or headphones your audience will use. A voice that is rich in studio headphones can be muddy on a laptop. If every voice scores poorly on clarity, write that down; it may mean the test line is too hard, or the tool’s library is thin for this role. If your school tool has no suitable voice, your own voice or a signed volunteer is a fully valid route. Use the record template below for every voice you consider, including the ones you reject.
Film: ______ Role: ______ Date: ______ Voice brief (age, energy, pace): ______ Voice name or ID: ______ Source (library voice / my own voice / consenting person): ______ License or consent (terms read on [date]; or signed authorization, signer, date): ______ Intended use (scenes, where it will be shown, how long): ______ Scores: fit /3 clarity /3 representation /3 legal use /3 Decision (cast / reject) and one-sentence reason: ______
Studio task: Audition three permitted voices and select one using stated criteria.
Cast the voices for your own film. Start with the lead and the narrator if there is one.
Checklist before you submit:
State the evidence that makes the selected voice usable.
Deliverable: Voice casting and authorization record.
Submit the voice casting and authorization record. The file must use the course naming convention and include enough process evidence to show the student's decisions and revisions.

| Criterion | Advanced | Proficient | Developing | Beginning |
|---|---|---|---|---|
| The work addresses the stated story or production purpose. | Casting is clearly tied to character and story, and the voice brief anticipates how the voice will serve key scenes. | Casting fits the characters and story, and the choice is explained with stated criteria. | Casting is partly explained; the link to character or story is thin. | Little evidence that casting served the story. |
| The student applies the required method accurately and produces usable capstone evidence. | Three permitted voices are auditioned on the same line, scored fairly, and the record is complete and checkable by a stranger. | Three permitted voices are auditioned and scored; the record has all required fields. | Fewer than three auditions, or the record is missing a field. | No fair audition and no usable record. |
| The student identifies at least one quality issue and records a meaningful revision decision. | Identifies a real quality or representation issue in the casting and records a specific revision, such as a changed voice or a rewritten brief. | Identifies at least one issue and records a meaningful revision decision. | Notes an issue but records no clear decision. | No issue or revision recorded. |
| The work complies with consent rights attribution privacy disclosure and school policy. | Every voice has a documented, authorized source; the record states a back-up route; nothing resembles an identifiable person. | Every voice has an authorized source and a clear permission note. | Permission is documented for some voices but not all. | Uses an unauthorized voice or imitates an identifiable person. |
Requirement: Never clone or imitate an identifiable person without documented permission.
Treat a voice like a person’s signature. If you cannot show where permission came from, do not use the voice. Never put the name of a real person, living or recently departed, into a voice tool in order to sound like them, and never record someone secretly. If a consenting person signs, keep the paper (or a scan) with your film files, tell them where the film will be shown, and respect a request to withdraw before release. Whenever a synthetic voice carries significant dialogue or narration, plan to disclose that in your credits. If you are unsure whether a voice is allowed, ask your teacher before you build anything on it.
