Definition
Viva voce (Latin: "with living voice") means by spoken word, aloud, or orally. In legal usage the term appears in two principal contexts:
1. Testimony. A witness testifies viva voce when giving evidence aloud in open court, in person and subject to live examination, as distinguished from testimony submitted in written form by deposition or affidavit.
2. Voting. A vote cast viva voce is one spoken openly — the voter states their choice aloud — as distinguished from a vote cast by written ballot in secret. In legislative bodies, a viva voce vote typically means members call out "aye" or "nay" in response to a question put from the chair.
Common Language
Modern common usage (Wiktionary): "By word of mouth; orally." Used in academic and formal contexts to describe oral examinations, defenses, or proceedings.
Historical common usage (Webster's 1913): "With the living voice; by word of mouth; orally." Webster's notes its use in the phrase "viva voce examination."
The gap between common and legal meaning is narrow here, but the legal term carries specific procedural weight in both contexts. In ordinary English "viva voce" simply means spoken rather than written. In law, it signals a formal procedural posture — open-court testimony with confrontation rights attached, or a publicly recorded legislative vote — not merely any oral communication.
Common Confusion
Viva voce testimony is sometimes loosely equated with any oral statement, but the term carries a more precise procedural meaning: testimony delivered in open court, subject to cross-examination, under oath, before the trier of fact. An oral statement to an investigator or a phone call is not viva voce evidence in the legal sense. Similarly, a voice vote in a legislature (where the collective sound determines the outcome) and a viva voce vote (where individual members' choices are recorded aloud) are related but not identical procedures in all parliamentary systems.
Why It Matters in Research
The term spans two distinct procedural domains — evidence law and legislative/electoral procedure — and researchers must identify which context controls before drawing conclusions from a source.
In evidence research, viva voce is the historical baseline against which written substitutes (depositions, affidavits, written interrogatories) are measured. The preference for viva voce testimony in common law courts underpins the Confrontation Clause tradition; understanding this preference is essential when tracing the development of hearsay doctrine, the admissibility of depositions at trial, and the rules governing remote or pre-recorded testimony. Sources from different eras will describe the same procedural preference with different emphasis: older materials treat viva voce as the obvious norm and written substitutes as the exception requiring justification; modern materials may treat them more symmetrically.
In electoral and legislative research, viva voce voting was the dominant method in early American elections before the secret ballot was broadly adopted in the late nineteenth century. Researchers working in historical election records, constitutional convention debates, or early legislative journals will encounter viva voce voting described neutrally — it was the standard, not a peculiarity. The shift away from viva voce voting toward written ballot is a significant political history data point; sources before and after that transition use the term very differently in tone. Early state constitutional provisions sometimes explicitly required or permitted viva voce voting; later amendments removed or restricted it.
Cross-corpus trap: A source discussing viva voce in an evidence context and a source discussing it in an electoral context may appear to contradict each other or to be discussing an archaic procedure when they are simply addressing different domains. Flag the domain before treating the source.
Historical Dictionary Support
Bouvier's entry is admirably concise and captures both principal uses: testimony delivered "in open court" as opposed to deposition, and the legislative vote spoken aloud as opposed to ballot. Bouvier does not elaborate on the evidentiary weight or procedural consequences of each form, but the opposition structure he provides — viva voce/deposition and viva voce/ballot — correctly maps the two domains researchers will encounter.
What Bouvier does not address: the constitutional dimensions of viva voce testimony (confrontation rights, the hearsay rule's preference for in-court witnesses), the historical transition from viva voce to secret ballot elections, or the parliamentary distinctions between a collective voice vote and an individually recorded oral vote. Researchers relying solely on Bouvier's entry will have the right framework but will need supplemental sources for any procedural depth.
Jurisdictional Note
In American legislative procedure, viva voce votes remain standard for routine measures; a recorded roll-call vote is typically required upon demand by a specified number of members. State constitutional provisions vary on when recorded votes are mandatory. In electoral law, secret ballot statutes have displaced viva voce voting in all U.S. general elections, though some jurisdictions retained viva voce procedures for certain local or party elections into the twentieth century.
