DeepSound Technology (deepsound.cn) is an AI voice and digital human technology service under Guangzhou DeepSound Technology Co., Ltd. It positions itself as an AI company focused on “intelligent voice and digital human technology.” The site highlights core capabilities including digital humans, speech recognition, speech synthesis, custom voice cloning, plus a developer center and OpenAPI documentation.
Based on the crawled content, DeepSound’s product lineup is mainly B2B-oriented: general speech synthesis, Cantonese speech synthesis, emotional speech synthesis, voice cloning, speech recognition, and digital human video generation. Typical use cases include TTS for smart speakers, dubbing services, audiobooks, intelligent customer service, virtual human short videos/live streaming, and AI virtual idols. Its lightweight lip-sync digital human API supports uploading a 15–60 second reference video and driving the character to speak or sing using audio, without model training, making it suitable for generating marketing videos at scale.
DeepSound’s API uses HTTP 1.1 and follows RESTful conventions, with the base URL at https://api.deepsound.cn/. The digital human API includes task creation, status querying, and callbacks, with support for task progress, failure/timeout states, and callback retries. Technical limitations are disclosed fairly clearly: audio must have an SNR of at least 15dB and be no longer than 2 hours; video must be 360P or above, and there must be exactly one face in the frame. Generated video links are valid for 3 days.
The site does not disclose pricing, free quotas, trial rules, or payment methods; only an “online demo” entry point is visible. Data privacy information is also limited, especially for voice cloning, where authorization, voiceprint abuse prevention, and data retention are important concerns. The contact section includes fields for company phone, business cooperation, and technical support, but the crawled content did not show specific contact details.
The main strengths are its broad capability coverage and clear focus on Chinese-language voice scenarios, especially Cantonese and emotional speech synthesis. It also lists partnership cases with Xiaomi, OPPO, Tencent Music, WPS, NetEase Cloud Music, and others. The drawbacks are limited pricing transparency and insufficient information on quality metrics and privacy compliance. It is best suited for enterprises, content platforms, in-vehicle/smart hardware manufacturers, and developer teams that need speech synthesis, custom voices, or large-scale digital human video production.
As a China-registered website, it should generally be directly accessible from mainland China, with lower network and payment barriers than similar overseas services, though specific payment methods are not disclosed. Comparable alternatives include iFlytek Open Platform, Baidu AI Cloud Speech, Alibaba Cloud Intelligent Speech Interaction, Tencent Cloud Text-to-Speech, and Volcano Engine Speech Technology.
