Businesses that need natural-sounding audio across products, content, languages, or accessibility features can use AI text-to-speech (TTS) technology to generate spoken content efficiently and consistently. An AI text-to-speech specialist brings the technical expertise to configure, integrate, and optimize these systems for specific applications and audiences.
What does an AI text-to-speech specialist do?
An AI text-to speech specialist handles the technical work of turning written text into synthesized speech using TTS platforms, APIs, and related tools. They configure voices, pronunciation, pacing, and other available speech settings and integrate voice generation into applications and content workflows. Their focus is producing reliable, intelligible audio voice that meets the requirements of the intended use.
Typically, AI text-to-speech specialists perform these tasks:
- Build integrations with speech-synthesis services such as Azure Text to Speech, Amazon Polly, or Google Cloud Text-to-Speech
- Write Speech Synthesis Markup Language (SSML) when supported to control elements such as pauses, emphasis, and pronunciation
- Select and configure voices, languages, speaking styles, and available speech parameters for the intended audience and use case
- Integrate audio generation into application or content workflows and handle request failures, retries, and error responses
- Test synthesized samples for pronunciation, clarity, pacing, and consistency across different types of content
- Create pronunciation rules or custom lexicons for names, acronyms, technical terms, and other specialized vocabulary when supported

Step 1: Post a job
Start by describing your use case and speech-synthesis requirements in a clear job post.
- Specify the use case, target languages and voice requirements
- List preferred TTS services, such as Azure, Amazon Polly, or Google Cloud
- Note any SSML or custom pronunciation requirements
- Describe required audio formats and application integrations
- Define deliverables, such as SSML templates or integration code
- Share your timeline and budgetย
- Adapt this AI engineer job description to your project
The Job Post Generator powered by Umaโข, Upwork's Mindful AI, drafts a full post from a few sentences about your needs. On Upwork, the average time from job post to first proposal is just three hours.
Step 2: Evaluate candidates
Review candidates for relevant TTS experience and evidence of reliable speech-synthesis integrations.
- Look for working TTS integrations similar to your use case
- Check experience with your preferred APIs and languages
- Review samples for pronunciation, clarity, pacing, and consistency
- Confirm experience with SSML when your project requires it
- Look for reliable error handling and production deployment experience
Uma can run instant video interviews and build shortlists with side-by-side candidate comparisons to speed your review.
Step 3: Interview your top choices
Use interviews to understand how candidates approach voice quality, pronunciation, and technical integration.
- Ask how they select and configure voices for different use cases
- Discuss how they handle names, acronyms, and technical terms
- Ask how they troubleshoot pronunciation or language issues
- Explore how they manage generated audio in your application
- Discuss testing for quality, latency, and reliability
- Adapt these AI engineer interview questions as a starting point
Schedule and conduct interviews within Upwork Messages, and get an immediate transcript and summary after each session.
Step 4: Agree on scope and begin work
Confirm deliverables, quality requirements, and milestones before work starts.
- Define supported languages, voices, engines, and audio formats
- Set milestones for integration, testing, tuning, and deployment
- Establish acceptance criteria for pronunciation and audio quality
- Define latency or processing requirements when relevant
- Confirm deliverables such as code, SSML, lexicons, and documentation
- Clarify voice licensing and usage rights when applicable
Use messaging and the contract workroom to communicate and manage the project. Identity verification, Hourly Payment Protection, hourly tracking, and project funds keep the engagement secure.
