HeyGen: HeyGen Voice Turbo (free)

{"about":"### From prepared text to spoken audio\n\nHeyGen Voice Turbo is a variant of HeyGen’s own voice model with an accelerated synthesis mode. You supply prepared text and the model generates a spoken rendition. The result can serve as the soundtrack to an explanation, a segment of learning material, a character’s line or a voiceover for a product message.\n\n### What the output provides\n\nThis Ailoot API listing provides a **text → speech** workflow. Start with the complete text you want someone to hear: the model handles the voiceover, so prepare the narrative structure, facts and required line length in advance. For longer material, divide the script into meaningful sections and review them separately.\n\nTurbo belongs to the same HeyGen Voice family and is designed for a shorter generation stage. This describes the model’s operating mode; the time taken to obtain a particular result depends on request processing. When reviewing a voiceover, assess not only the vocal tone but also how pauses, questions, lists, names and specialist terms in your text sound.\n\n### Practical uses\n\n- Voice a short explanation of a product feature or a set of instructions.\n- Prepare a spoken segment for editing into a video.\n- Turn an educational paragraph into audio material.\n- Listen to a draft script and revise phrases that are difficult to follow by ear.\n\nA useful sequence is to express one complete idea, generate the speech, listen to the pronunciation and pace, then save a successful version for further use. If a sentence is hard to understand when heard, split it, expand an abbreviation or write an ambiguous number in words, then generate speech from the revised text.\n\n### Text and pronunciation\n\nHeyGen’s official speech interface is designed for ordinary prose of up to **5,000 characters** per request. A clear script helps control the recording’s content: punctuation, short sentences and consistent terminology make lines easier to follow. Check the resulting accent and name pronunciation against real material.\n\n### Capabilities of this listing\n\nThe method available here accepts text and returns generated speech. You can use the voiceover in further audio work or video editing. Creating visuals, controlling an avatar, translating an existing video and creating a voice clone belong to separate workflows; this method specifically provides speech synthesis from text.","alias_of":null,"aliases":[],"author":"HeyGen","canonical_model":"heygen/heygen-voice-1-turbo:free","ctx":null,"formats":["speech"],"id":"heygen/heygen-voice-1-turbo:free","input":["text"],"kind":"speech","max_out":null,"methods":[{"cache_read":null,"cache_write":null,"cache_write_1h":null,"cache_write_5m":null,"conditional_meter":null,"ctx":null,"family":"openai","fast_multiplier":null,"flex_multiplier":null,"fmt":"speech","http":"POST","img_in":null,"img_out":null,"in":null,"input":["text"],"label":"Озвучка текста","max_out":null,"max_tool_calls":null,"out":null,"output":["speech"],"path":"/v1/audio/speech","request_model_id":"heygen/heygen-voice-1-turbo:free","route_label":"Ultra","status_reads":[],"tiers":[],"tool_prices":null,"unit":"request","units":[{"key":"per_request","label":"за запрос","side":"out","usd":0}]}],"model_aliases":[{"canonical_model_id":"heygen/heygen-voice-1-turbo:free","request_model_id":"heygen/heygen-voice-1-turbo:free","route_label":"Ultra"}],"name":"HeyGen: HeyGen Voice Turbo (free)","price":{"in":null,"in_label":null,"out":0,"out_label":"за запрос","sort_in":null,"sort_out":null,"varies":false},"public_id":"heygen/heygen-voice-1-turbo:free","short":"Turns prepared text into HeyGen speech for videos, explanations and audio content."}
