Conversations by NLX can mimic the tone and emotion, language, and the way a human talks, along with the necessary knowledge a human has for practicing conversations without actually doing it.
Senior Tech Engineer at a tech services company with 5,001-10,000 employees
When the bot is not able to resolve an issue, it performs a warm handoff to a live agent, passing the full context of the conversation so that the customer never has to repeat themselves.

Conversations by NLX provides the same kind of web-based studio where you drag and drop blocks, connect them, and wherever required, you write business logic primarily using JavaScript.

Featured Reviews

Suhas Palani - PeerSpot reviewer
Full Stack Developer at Tundra Technical Solutions
Automation has transformed tier-one support and now reduces wait times while improving handoffs
One area for improvement in Conversations by NLX would be the initial learning curve for setting up some of the more advanced integrations with our older legacy systems. We occasionally encounter small hiccups where the bot has trouble maintaining context across a very long, multi-turn conversation. Having even more robust, out-of-the-box reporting features would also be a fantastic addition for deeper analysis. More comprehensive documentation for Conversations by NLX with more detailed code examples and a more centralized developer hub would make the initial development and debugging process much smoother. The main things holding Conversations by NLX back from a higher score of 9 or 10 are the hurdles we faced during the initial setup with our old legacy systems and the need for more in-depth documentation to support developers. Those context gaps during longer conversations also mean it is not quite at a perfect level yet.
Arunkumar HG - PeerSpot reviewer
Technology Architect & Hands-On Leader | Prototyping, Automation, AI/LLM Integration | 20+ Years in at Regalix
A Powerful, Adaptable, and Constantly Evolving STT Solution for Voice Automation
Honestly, Deepgram has been exceptionally proactive in addressing the primary area that needed improvement. My main challenge was with the real-time detection of when a user has finished speaking in a live conversation, which is critical for a responsive voice bot. They directly solved this by releasing their Flux model. Because Flux is a recent release, I haven't yet had enough time to thoroughly test it and identify new limitations. At this stage, any "improvement" would be more of a "nice-to-have" feature rather than a fix for an existing problem. The core service is already very robust and meets all of our current needs. What additional features should be included in the next release? ---------------------------------------------------------------- Looking toward the future, here are a few features that could add even more value to an already excellent platform: * Advanced Built-in Analytics: While I can get the raw transcript and build my own analytics pipeline, it would be powerful to have features like sentiment analysis, emotion detection, or automatic summarization offered directly through the API. This would save significant development time. * More Granular Speaker Diarization: For calls with multiple participants, enhancing the real-time speaker diarization (labeling who is speaking) to be even more precise would be a fantastic addition for creating detailed call analyses. * Tighter Integration with TTS: Since Deepgram is also expanding into Text-to-Speech (TTS), offering a more seamlessly integrated STT-to-TTS pipeline could simplify the development stack for creating voice agents from start to finish. * Specialized, Pre-Trained Industry Models: While the general models are highly accurate, offering even more specialized, pre-trained models for specific industries like finance, healthcare, or legal-which are heavy on specific jargon-could push the accuracy even higher for those niche use cases.
