Introduction

Qwen-Audio 3.0 TTS Plus gives social and companion apps an expressive preset cast from Alibaba's Qwen team. The 597 voices include 589 Chinese presets and eight English presets for character dialogue and conversational recordings.

Keep the dialogue in text, then describe the personality and feeling in instructions. Synthesis runs asynchronously: submit a request, poll its task and review the resulting speech before using it in your app.

Key features

• Audition eight English voices alongside a catalog of 589 Chinese presets.
• Describe a companion's mood or a coach's energy using free-style performance notes.
• Adjust speed from 0.5 to 2 and pitch from 0.5 to 2 for a chosen character.
• Add SSML pronunciation, emphasis and pause markup when dialogue needs closer control.

Request parameters

Pricing

Prices are in USD. The API uses a separate USD balance. Website credits cannot be used or transferred to it, and API funds cannot be transferred to website credits. When a task is accepted, we reserve the maximum quoted amount from your API balance. On completion, we charge for actual usage, never more than the hold, and release the remainder. If the task fails, the hold is released.

Send the same request body to POST /jobs/quote to see the estimated and maximum USD charge before running. A quote does not run the task or charge your balance.

Use cases

• Companion conversations: Write a supportive reply and audition a soft, playful performance for a fictional companion.
• Social app characters: Give each character a chosen preset and a short persona direction for their spoken posts.
• Coaching encouragement: Pair a workout script with upbeat guidance that carries encouragement through the final repetition.

Prompt guide & pro tips

• Define the character's manner before tuning individual sliders. Example instruction: "Sound friendly, curious and a little playful."
• Use one emotional intention per audition to make comparisons easier. Example instruction: "Offer reassurance with gentle, steady confidence."
• Keep coaching direction separate from the words of encouragement. Example instruction: "Speak like an upbeat gym coach cheering the final set."
• Compare a short reply in several presets before choosing a cast member. Example instruction: "Read with relaxed warmth, as if catching up by phone."
