The phrase "spoke haltingly" is often used to describe someone who speaks with a hesitant or stuttering tone. To describe the opposite of this, one could use words that signify confident and fluent speech, such as "enunciated clearly," "spoke fluidly," "communicated with ease," "elocuted confidently," or simply "articulated smoothly." A person who speaks without hesitation and with clear language can be described as "articulate," "eloquent," "fluent," or "well-spoken." It is important to note that people may speak haltingly for various reasons, including anxiety, lack of self-confidence, or a speech impediment, and it is important to approach differences in speech patterns with sensitivity and understanding.
