Text to Speech Best Practices

Writing Text for Synthesis

• Punctuate deliberately - commas and periods control pacing, not just grammar. Under-punctuated text tends to sound rushed.
• Spell out abbreviations and numbers that could be read multiple ways (e.g. dates, currency) if you notice mispronunciation.
• Match the language dropdown to the actual language of your text - a mismatch is the most common cause of mispronounced words.

Choosing Speed and Tone

• Use slower speeds for narration, instructional content, and anything where authority or clarity matters.
• Use faster speeds for ads, promos, and social content where energy matters more than precision.

Keeping a Consistent Voice

• Pick a persona once per project and reuse it across every asset - switching personas mid-project is the most common reason a series of clips ends up sounding disjointed.
• If you’ll reuse a persona across Text to Speech and Dubbing, select it in the Voice Library once rather than re-picking it in every tool.
• Generate a short test line before committing to a long script - catching a mispronunciation or awkward pacing choice on one sentence is far cheaper than after synthesizing several paragraphs.
