Our voice AI development services turn spoken language into reliable, low-latency software — speech-to-text that understands real accents, text-to-speech that sounds natural, and voicebots that hold a conversation without falling apart on the third turn. We design the full pipeline: capture, transcription, intent, response, and synthesis, all inside a latency budget your users will actually tolerate.
As a voice AI company shipping since 2016, we have delivered 250+ projects for 100+ clients across 20+ countries. We do not stop at a demo. We engineer barge-in, fallback paths, telephony integration, accuracy tuning, and privacy controls so your voice experience survives contact with production traffic, background noise, and edge-case callers.
Voice AI is the engineering discipline that lets software listen, understand, and speak. It combines automatic speech recognition (ASR/STT) to convert audio into text, natural language understanding to extract intent, dialogue logic to decide what happens next, and text-to-speech (TTS) to respond out loud — all stitched into a low-latency pipeline that feels like a conversation rather than a form.
The hard part is not any single model; it is the system around it. Production voice AI has to handle noisy microphones, overlapping speech, accents, interruptions (barge-in), and network jitter while staying inside a sub-second response budget. It also has to fail gracefully — routing to a human, replaying a prompt, or confirming uncertain input — so a misheard word never becomes a broken transaction. That orchestration is what separates a convincing demo from a deployable product.
Hands-free assistants embedded in mobile, web, automotive, or wearable apps. We wire up wake-word handling, streaming STT, intent routing, and natural TTS replies so users can ask, command, and confirm by voice — with visual fallbacks when speech is the wrong channel.
Streaming and batch ASR tuned for your domain vocabulary, accents, and audio conditions. We add custom dictionaries, punctuation and diarization, confidence scoring, and post-processing so transcripts are accurate enough to drive downstream automation, not just display.
Natural, on-brand synthesized voices for prompts, narration, and replies. We integrate neural TTS, SSML control over pacing and emphasis, multilingual output, and — where consented and compliant — custom voice cloning for a consistent brand persona.
Conversational phone agents that replace rigid menu trees. We connect to telephony over SIP, handle barge-in, capture intent in natural language, integrate with your CRM and ticketing, and hand off to live agents with full context when needed.
Bidirectional, low-latency voice for live agents, copilots, and in-app conversations. We engineer streaming audio, partial transcripts, interruption handling, and tight latency budgets so the exchange feels immediate rather than walkie-talkie.
Voice-driven accessibility, live captioning, meeting and call transcription, and searchable audio archives. We add speaker labels, timestamps, and redaction so transcripts are usable, compliant, and inclusive.
A senior engineer will tell you whether voice fits your workflow, where a tap or screen beats a microphone, and what it takes to ship it inside a real latency budget.
Voicebots deflect routine calls — balance checks, order status, appointment changes — and escalate the rest to humans with context attached. The result is shorter queues and agents focused on the calls that actually need them.
Warehouses, field service, clinical settings, driving, and the kitchen floor. When hands are occupied, voice capture and confirmation keep work moving without forcing users to stop and tap a screen.
Speech-to-text plus translation plus text-to-speech enables cross-language conversation and content. This is where voice meets reach — letting one app serve speakers across many of the 20+ countries our clients operate in.
Voice is the wrong default for dense data entry, high-precision numeric input, sensitive information in public spaces, or noisy environments without a headset. We will tell you when a tap, type, or hybrid flow beats a microphone — and design accordingly instead of forcing voice for its own sake.
We map intents, utterances, confirmation points, and failure paths before writing model code. We decide what belongs to voice versus screen, script prompts and re-prompts, and define what “good enough” accuracy means for each step so the experience is engineered, not improvised.
We assemble streaming ASR, intent handling, and neural TTS, then optimize for a target response budget — typically aiming for sub-second perceived latency. We engineer barge-in, partial transcripts, endpointing, and streaming synthesis so the conversation feels live.
We add confidence thresholds, confirmation prompts, and human handoff for low-certainty turns. We define data handling, retention, redaction, and consent — including on-prem or in-region options — so accuracy and privacy are enforced by design, not left to chance.
We instrument call and session analytics — recognition accuracy, drop-off, handoff rates, latency — and feed real traffic back into vocabulary, prompts, and model choices. Voice systems improve with usage, and we keep tuning after launch.

We are a voice AI company with a delivery record, not a pitch deck. 250+ projects delivered for 100+ clients across 20+ countries means we have built, launched, and maintained real software — including speech and translation apps in production.
We own the whole loop: capture, STT, intent, dialogue, TTS, telephony, and integration. You get one accountable team for the voice experience instead of stitching together point vendors who each blame the next.
We design barge-in, fallback, and confidence handling from day one. The difference between a demo and a product is what happens on the unhappy path, and that is where we spend our engineering.
On-prem, in-region, and redaction options for sensitive voice data — and you own the code, models, and infrastructure. No lock-in to a black box you cannot inspect or move.
Mobilions' clients describe fast delivery, clear communication, and senior, trustworthy engineering—in their own words.
Great experience working with this team. They completed the development work quickly and efficiently without wasting time. Communication was clear and consistent, they understood the requirements well, gave smart suggestions, and delivered exactly as discussed. I'd highly recommend them to anyone looking for a reliable, fast, and skilled app development team.
We worked with Ankit, Mayur, and Tushar to build the first version of Baba Hebrew for iOS and Android, and they delivered super fast. The team was responsive, reliable, and efficient, taking the idea from zero to a working app in record time. I'd recommend them to anyone who wants to get an MVP live quickly.
Tushar and Ankit did an outstanding job developing our native iOS (Swift) and Android (Kotlin) apps. They were efficient, responsive, and technically strong throughout. Thanks to their work, we launched successfully and gained over 1,000 users in the first 30 days. Highly recommend this team for quality mobile app development.
It was a wonderful experience working with Tushar, Ankit, and their team. They built a great mobile app for me and truly brought my vision to life. What stood out was not just their technical skill but their attitude: always positive, solution-oriented, and incredibly patient. They went above and beyond at every step, finding creative workarounds and staying committed even when things got challenging. Extremely professional and trustworthy. I would absolutely hire them again.

Voice AI is software that can listen, understand, and speak. It chains together automatic speech recognition (ASR/STT) to turn audio into text, natural language understanding to extract what the user means, dialogue logic to decide the next step, and text-to-speech (TTS) to reply out loud — all inside a low-latency pipeline so it feels like a conversation. The engineering challenge is the system around the models: handling noise, accents, interruptions (barge-in), and network jitter while staying inside a response budget, and failing gracefully when input is uncertain. Done well, voice AI powers assistants, phone voicebots, real-time interfaces, and transcription. Mobilions builds the complete loop, not just a single model, so the experience holds up under real production traffic rather than only in a controlled demo.
We build voice assistants, speech-to-text pipelines, text-to-speech and voice cloning, voicebots for IVR and phone, real-time in-app voice interfaces, and transcription and accessibility tooling. Most projects combine several of these into one production system.
Speech-to-text (STT/ASR) converts spoken audio into written text the system can act on. Text-to-speech (TTS) does the reverse, turning text into natural-sounding spoken audio. A full voice experience uses both: STT to understand the user and TTS to respond.
Accuracy depends on audio quality, vocabulary, and accents, so we tune for your conditions rather than quoting a single number. We add custom dictionaries, domain language, confidence scoring, and confirmation prompts, and we test against real recordings from your users and accents before launch.
Yes. We engineer streaming STT, partial transcripts, endpointing, barge-in, and streaming TTS to target sub-second perceived latency. Real-time voice is a core focus, and we treat the latency budget as a hard requirement, not an afterthought.
Yes. We connect over SIP and PSTN for telephony and WebRTC for in-app audio, handle call control and barge-in, and integrate with your CRM and ticketing. Voicebots can replace rigid menu trees and hand off to live agents with full context.
We select STT and TTS engines for the languages and accents you need, including multilingual and translation flows. Our clients operate across 20+ countries, and we have shipped speech and translation apps such as Baba and Careslate.
We offer on-prem, in-region, and self-hosted model options for sensitive voice data, plus redaction, retention controls, and consent capture. For regulated work like healthcare or fintech, we design data handling into the architecture from the start.
Cost and timeline scale with scope: a focused transcription or assistant feature is far smaller than a multilingual telephony voicebot. After a short discovery, we provide a fixed estimate and phased plan. For broader options, see our AI chatbot development services.
You do. We deliver the source code, model configurations, and infrastructure setup, with no black-box lock-in. You can host, inspect, and extend the system independently of Mobilions.
