Text to Audio for Narration

Begin with the delivery context. Is the line a product walkthrough, an accessibility readout, a video voiceover, or a conversational response inside an app? Each has a different acceptance test. A voiceover should fit its scene without forcing the editor to cut important words. A readout should pronounce names, abbreviations, and numbers clearly. An app response may need a consistent voice over many short requests. Write the script as it should be spoken. Break long sentences at natural pauses and check unfamiliar names separately. Use one support message as the running test: "Mira, your order 1,250 is ready for pickup." Its name, number, and pause provide several listening checks without changing the source script.

The Seed Speech TTS 2.0 API reference documents a required `text` field and optional voice, language, speed, pitch, volume, and voice instruction fields. Those controls belong to that model. Another speech model may expose a different set, so choose the model first and use its current request schema. Test one variable at a time. Hold the script constant while comparing two voices; then keep the preferred voice while adjusting delivery. If a pronunciation is wrong, revise the written input or try an instruction supported by the selected model. Do not judge a new voice using a different script, because that hides whether the voice or the words caused the change.

Seed Speech TTS 2.0 lists MP3 and Opus output formats. Choose the one accepted by your player, editor, or delivery pipeline. If a video editor requires a particular container, confirm it before generating a large set of lines. Keep the script, model identifier, voice choice, and exported file together so later corrections do not become guesswork. Inspect the entire download for silence, clipped words, and misplaced pauses. For video, place it against the picture. A shorter script may fit better than speeding up the voice unnaturally.

For an application, the speech generation guide shows a request path, while each model reference defines its fields. Test representative scripts, record settings, and store approved files in your own system. Separate three adjacent jobs in your product design. Text-to-audio generates speech from words. Speech-to-text transcribes an existing recording. Audio-for-video may create music, sound effects, or dubbing. Choosing the correct job early keeps the UI, pricing check, and review process aligned with what users expect to receive.
