We build AI systems that work — not prototypes, but production infrastructure. Our core is agentic AI: autonomous agents, LLM integrations, and predictive ML models designed to operate inside your existing workflows and make real decisions. What sets us apart is the stack we pair it with. We implement Odoo ERP end-to-end, design and manufacture custom IoT hardware, and deliver across the full web and mobile stack. This means we can put AI where others can't — on edge devices, inside ERP workflows, reading live sensor data, acting on it in real time. We work across React, Flutter, Django, Node, and deploy on AWS, GCP, and Azure. Our hardware work spans PCB design, ESP32/STM32 firmware, and MQTT-connected sensor networks. If your project crosses boundaries — AI that talks to hardware, agents embedded in enterprise software, intelligent systems that need to actually ship — that's exactly where we do our best work. Tell us what you're building.
A Speech Synthesis Expert is a specialist who designs, trains, and deploys text-to-speech (TTS) systems that convert written text into natural-sounding human speech using AI and signal processing techniques. These freelancers build the voice layer behind virtual assistants, audiobooks, IVR systems, accessibility tools, and dubbed media. Hiring a speech synthesis expert means commissioning custom voice models, voice cloning pipelines, and production-grade TTS integrations that sound expressive, intelligible, and on-brand.
A speech synthesis specialist produces working voice systems, not just research notebooks. Deliverables typically include trained acoustic and vocoder models, fine-tuned voice clones, synthesis APIs, and pronunciation lexicons aligned to your domain vocabulary. They also handle the audio engineering that makes synthetic speech sound human: prosody control, SSML markup, emotion and style tokens, and noise-free output suitable for broadcast or product use.
Commercially, the work matters because voice is a brand asset. A consistent, intelligible synthetic voice reduces narration costs across video, e-learning, and IVR, and accelerates localization into new languages. A skilled TTS engineer compresses what used to be weeks of studio recording into a reusable voice model that scales to thousands of hours of output.
Speech synthesis experts work across open-source and cloud-based stacks. On the modeling side, they typically use frameworks such as Tacotron 2, FastSpeech 2, VITS, Glow-TTS, Tortoise-TTS, Coqui TTS, ESPnet, NVIDIA NeMo, and Mozilla TTS. Vocoders include HiFi-GAN, WaveGlow, WaveRNN, and Universal MelGAN. Foundation work is built in PyTorch and TensorFlow, with audio processing in Librosa, SoX, FFmpeg, and Praat.
For production deployment, they integrate with cloud services such as Amazon Polly, Google Cloud Text-to-Speech, Microsoft Azure Speech, ElevenLabs, and IBM Watson, or self-host inference using ONNX, TensorRT, or Triton Inference Server. SSML is the standard markup language for controlling speech output, and forced alignment tools like the Montreal Forced Aligner are used for dataset preparation.
Strong candidates demonstrate both machine learning depth and audio engineering instincts. Look for portfolios containing audio samples of trained voices, before-and-after cloning demos, and documented MOS evaluations. Experience with at least one neural TTS framework (VITS, FastSpeech, or Tacotron) and one neural vocoder (HiFi-GAN or WaveRNN) is a baseline expectation. Bonus signals include published papers, open-source TTS contributions, multilingual project history, and familiarity with phonetics and IPA notation.
Useful interview questions:
Freelancer.com gives you access to a global pool of speech synthesis experts spanning machine learning researchers, audio engineers, and TTS application developers. You can post a project on Freelancer.com and receive competitive bids within hours, then compare portfolios, listen to voice samples, and review verified ratings before committing. Whether you need a single voice clone for an audiobook or a full multilingual TTS pipeline for a product launch, freelancers on Freelancer.com cover the full spectrum of speech AI work, with budgets you control and Milestone Payments protecting every engagement.
Ready to bring a custom voice to life?
Hiring a speech synthesis expert is a structured process that hinges on a precise brief, careful proposal review, and evidence-based candidate evaluation. Because TTS work blends ML, audio engineering, and linguistics, your brief and shortlist need to reflect all three. The steps below show how to move from a project idea to an awarded engagement on Freelancer.com.
The project post is the single biggest determinant of bid quality, because a clear brief filters for candidates whose speech synthesis skills genuinely match your needs. Head to the
Bids are short proposals revealing how each freelancer interprets your brief, what architecture they propose, and what timeline they consider realistic. Read carefully — a strong speech synthesis bid will name specific models, describe a data pipeline, and raise informed questions about your dataset and target voice. Use Freelancer.com chat to clarify before shortlisting.
The final decision combines proposal quality with profile evidence. For speech synthesis, listen to portfolio audio with critical ears — consistency of naturalness, prosody, and intelligibility across multiple samples matters more than one polished demo. Weigh ratings, written reviews, and on-time delivery alongside technical depth.
A voice cloning project from a clean dataset can take one to three weeks, including data preparation, model training, and quality evaluation. Full custom multilingual TTS systems with deployment infrastructure typically run one to three months. Timelines depend on dataset size, target languages, and whether real-time inference is required.
Text-to-speech is the broader discipline of converting written text into spoken audio using a generic or branded voice. Voice cloning is a subset where the system replicates a specific person's vocal identity from reference recordings. Most modern speech synthesis experts handle both, since they share the same underlying neural architectures.
Not always. Few-shot voice cloning models like Tortoise-TTS, VITS variants, and commercial APIs can produce a usable voice from a few minutes of reference audio. Higher-quality, broadcast-grade voices still benefit from one to ten hours of professionally recorded studio data.
Yes. Experienced TTS engineers routinely build multilingual models, fine-tune accented variants, and implement code-switching for mixed-language text. They will typically advise on dataset requirements and phoneme inventories for each target language during scoping.
For defined deliverables — a single voice model, a TTS API integration, or SSML tuning — a skilled freelancer is usually faster and more cost-effective. Agencies make more sense only when you need ongoing voice operations across many languages and product surfaces simultaneously.
