Voice works for a narrow set of tasks and fails at everything else, which is exactly why it is worth building properly. Checking a balance, reordering a usual item, logging a reading with both hands occupied, or navigating a phone menu without pressing four keys are all faster spoken than tapped. TechEsperto builds Alexa skills, Google Assistant actions, in-app voice interfaces, and voice AI for customer service, scoped around tasks that genuinely benefit. If you have a voice idea, the first useful conversation is whether voice is the right surface for it.
AI chatbot development work.
We scope voice projects around the specific tasks that benefit from being spoken, then design carefully for the moments the system gets it wrong. The applications below reflect what brands, service providers, and enterprises most often bring us, delivered on platform assistants, in your own product, or in the contact center.
Branded voice applications on the major assistant platforms, covering account linking, session handling, and the platform certification requirements that gate publication.
Voice input inside your mobile or web product, where you control the experience end to end and are not dependent on a platformโs discovery or policy decisions.
Natural-language phone handling that resolves routine enquiries and routes the rest accurately, replacing menu trees that customers navigate by pressing zero repeatedly.
Hands-free logging, lookup, and confirmation for technicians and warehouse staff, where speaking is faster than removing gloves to use a screen.
Spoken access to products and services for users with visual or motor impairments, which frequently improves usability for everyone else at the same time.
Experiences combining speech with a display on smart screens, in-car systems, and phones, using each channel for what it does best rather than duplicating both.
Voice applications are judged on how they behave when things go wrong, because misunderstanding is routine rather than exceptional. The capabilities below carry most of the experience, and they are where inexperienced voice builds usually fall short, producing systems that work in demonstration and frustrate users in daily life.
Prompts that set expectations about what can be said, with wording tested aloud rather than read on a page, since speech and text have different rhythms entirely.
Structured handling for no input, no match, and partial understanding, with escalating help that narrows the request instead of repeating the same prompt.
Explicit confirmation before anything that spends money, changes an order, or cannot be undone, since misrecognition on those actions destroys trust permanently.
Secure account linking and voice-appropriate authentication, with sensitive actions handed to a phone or app where speaking credentials aloud would be inappropriate.
Retention of context across turns so follow-up questions work naturally, rather than forcing users to restate everything with each request.
Clean escalation to a person or to your app when the request exceeds what voice should handle, carrying the conversation context so the user does not repeat themselves.
Voice projects need testing aloud, early and often, because written dialogue almost never survives being spoken. Our process puts working conversations in front of real users during development rather than at the end. Each stage produces a named deliverable, and the transcripts from early testing usually reshape the design more than any review meeting.
We identify which tasks genuinely benefit from voice and which channel fits, and we will recommend against a voice build where a screen would serve users better.
Dialogue flows, prompts, error paths, and confirmations written and read aloud, since the first draft of any voice script sounds wrong when spoken.
Working prototypes tested with real users speaking naturally, which reliably surfaces phrasings the design never anticipated and prompts that confuse rather than guide.
Implementation with connections to the systems holding the answers, because a voice interface without access to real account, order, or inventory data is a demonstration.
Platform certification for assistant applications, accuracy testing across accents and conditions, and staged launch with transcript review from the first day.
Ongoing review of what users actually said and where the system failed, which is the only reliable route to improving voice accuracy and coverage after launch.
Voice cost is driven by the number of tasks supported, how many backend systems must be reached, and whether telephony or contact center integration is involved. A single-task assistant skill is a modest engagement; natural-language call handling across a contact center is considerably larger. Related conversational work is covered on our workflow automation page.
A short fixed-price engagement assessing voice fit, designing the core conversations, and producing a scoped estimate for the build.
A defined scope of tasks and channels with milestones and acceptance criteria, appropriate where the use cases are settled and integrations are known.
A named team for programs expanding across tasks, languages, and channels, billed monthly, which suits contact center transformation work.
Transcript review, accuracy improvement, platform updates, and coverage expansion, scoped monthly since voice systems improve mainly through analysis of real usage.
Our work and story have been picked up by news outlets and databases worldwide.

Cost depends on how many tasks the system supports, how many backend systems it must reach, and whether telephony or contact center integration is involved. A single-task assistant skill is far smaller than natural-language call handling across a contact center.
A focused assistant skill typically takes weeks, including platform certification. Contact center voice AI takes longer because telephony integration, agent handoff, and accuracy testing across accents and call conditions all sit in scope.
It depends on the task. Short, frequent actions with few parameters suit voice well. Anything requiring comparison, browsing, or visual review does not, and we will recommend a screen-based approach where that is the honest answer.
Alexa and Google Assistant for platform skills and actions, in-app voice interfaces where you want full control, and contact center voice AI integrated with telephony. We recommend the channel based on where your users already are.
With structured reprompting that narrows the request, explicit confirmation before consequential actions, and clean handoff to a person or another channel. Misunderstanding is routine in voice, so recovery design carries most of the experience.
Yes. Voice systems improve mainly through reviewing what users actually said and where the system failed. Retainers cover transcript analysis, accuracy improvement, coverage expansion, and platform requirement changes.
