Baidu Text-to-Speech review
A developer-focused speech platform for Chinese long-form and application synthesis.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Baidu Text-to-Speech converts written text into generated speech for websites, applications, mobile apps, hardware, and connected devices. It is aimed primarily at developers and organizations building reading, broadcasting, assistant, education, hardware, and content-production products. Its coverage includes short-text, long-text, streaming, and offline synthesis, with web, Android, iOS, Linux, and API access. Long-text synthesis supports up to 100,000 Chinese characters per generation, making the service particularly suited to extended Chinese audio workflows.
The platform covers both hosted and embedded deployment needs. REST API access is complemented by Android, iOS, Linux, and HarmonyOS SDKs, while offline speech-synthesis SDKs provide an option beyond online generation. Streaming text-to-speech supports responsive application experiences, and adjustable speed, pitch, volume, and emotional expression provide control over delivery. Voice cloning from recorded audio adds customization, while pronunciation annotation for Chinese polyphonic characters addresses a specific Chinese-language synthesis requirement.
Pricing is split between long-text and short-text online synthesis. The long-text basic voice-library package is listed at ¥170 and is valid for one year. The short-text basic voice-library package costs CNY 1,200 as a one-time package valid for 12 months and includes 1,000 thousand calls and 100 concurrent calls. Baidu Text-to-Speech is a strong fit for Chinese long-form synthesis, multi-platform product integration, and deployments needing cloning or pronunciation controls. Teams seeking a simple consumer voice generator or a broader emphasis on non-developer workflows should consider a different type of tool.
