## audEERING

audEERING GmbH is a German company specialising in computational paralinguistics — the science of what the voice reveals beyond the words. Its core engine detects roughly 7,000 acoustic parameters covering phonatory, articulatory and prosodic aspects of speech, then maps those onto emotional states, speaker traits and health-related vocal biomarkers. Since 2025 audEERING has been part of the Agile Robots SE group, which broadened its reach into robotics and embodied AI.

The commercial offering is built around three products. devAIce is the flagship technology, delivered as an SDK, web API or plugin and bundling the company's models for embeddable empathic interaction. devAIce XR is a Unity and Unreal plugin that adds tone-of-voice understanding to immersive applications, while AI SoundLab is a GDPR-conscious audio data collection tool for building proprietary voice datasets. The company also publishes openSMILE, a widely used open-source feature extraction toolkit.

Because the technology is sold as licensed building blocks rather than an end-user app, buyers are typically product teams embedding emotion recognition, driver-state monitoring, call-centre analytics, XR avatars or clinical voice research into their own platforms. Pricing is quoted per project through a product request, and an academic licence is available for research use.

**Pricing & Plans:** Contact for pricing. audEERING quotes custom licences per project via product request; a dedicated academic licence is available for research and teaching use.

- **~7,000 acoustic parameters:** Voice analysis covering phonatory, articulatory and prosodic dimensions, forming the basis for expression and biomarker models.
- **Speech emotion recognition:** Detects and classifies emotional states from tone of voice to power empathic and responsive interfaces.
- **devAIce SDK, API and plugin:** Deploy the models as an SDK, a web API or a plugin, so the technology can be embedded into existing products.
- **devAIce XR for Unity and Unreal:** Adds expressivity understanding to VR, AR, MR and game-engine projects for more natural avatars and agents.
- **Vocal biomarkers and openness:** Explores vocal markers for specific diseases, supported by the open-source openSMILE toolkit and an active publication record.

**Strengths:** Deep, research-grounded audio feature extraction rather than a shallow wrapper; Multiple deployment paths: SDK, web API and engine plugins; Strong academic pedigree, with the widely used openSMILE toolkit and ongoing publications; Privacy and GDPR awareness built into the data-collection product

**Limitations:** No transparent public price list; every deal starts with a contact form; Aimed at integrators and enterprises rather than individual end users; Emotion recognition from voice raises ethical questions that buyers must address themselves

## Soniox

Soniox is a multilingual speech AI platform built for developers who need to power voice products. Rather than stitching together separate vendors for recognition, synthesis, and translation, it offers one unified API covering real-time speech-to-text, text-to-speech, and speech translation across 60+ languages and roughly 3,600 language pairs. The emphasis throughout is on doing the hard parts of voice AI well: high accuracy beyond English, seamless mid-sentence language switching, reliable handling of numbers and names, and low enough latency for live conversation.

On the recognition side, its STT models are marketed as highly accurate across accents, alphanumerics, domain vocabulary, and noisy, multi-speaker settings, with a newer model that recognises and filters out a voice agent's own speech. The text-to-speech line adds expressive control through audio tags, 200+ built-in voices tagged by gender, age, accent, and style, plus instant voice cloning from just a few seconds of audio. Translation handles code-switching environments where speakers change languages mid-sentence, and regional deployment lets teams run everything in-region for latency, data residency, and regulatory reasons, with audio processed in real time and never stored.

Soniox positions itself as enterprise-ready. Its site lists integrations with Perplexity, Genspark, Tana, and other platforms, and it publishes live side-by-side comparisons against providers like OpenAI, Google, Azure, Deepgram, Speechmatics, and AssemblyAI so developers can test on their own data. It is a paid API platform rather than a consumer app, aimed at teams building voice agents, wearables, dictation, and multilingual experiences at scale.

**Pricing & Plans:** Soniox is a paid API platform. Pricing is usage-based rather than a fixed consumer subscription, with plans and rates listed on its pricing page. There is no free consumer tier, so budget depends on your speech-processing volume and model choice.

- **Real-time speech-to-text:** Soniox STT delivers high accuracy across 60+ languages, accents, numbers, names, and domain vocabulary, engineered for fast multi-speaker conversations and noisy environments.
- **Text-to-speech and voice cloning:** Generate expressive speech in 60+ languages with audio tags, alphanumeric accuracy, seamless language switching, 200+ built-in voices, and instant voice cloning.
- **Real-time speech translation:** Translate speech in real time across roughly 3,600 language pairs, with low-latency output that starts before a sentence finishes and handles mid-sentence language switching.
- **Low-latency streaming:** Streaming models transcribe speech and start generating audio from the first few words, keeping interaction fast enough for live voice agents and captions.
- **Data residency and privacy:** Run STT and TTS in-region to meet latency, data residency, and regulatory needs, with audio processed in real time and never stored.

**Strengths:** One unified API for STT, TTS, and speech translation; Strong multilingual accuracy, including code-switching and alphanumerics; Low-latency streaming suited to live conversation and captions; Voice cloning and 200+ built-in voices for natural TTS

**Limitations:** Priced as an API platform, so cost scales with usage and needs developer integration; No consumer-facing free editing suite; it targets builders rather than end users; Advanced features like regional deployment may be limited during early access
