Common Mistakes to Avoid
Realistic TTS projects often fail due to control gaps, integration mismatch, or costs that rise faster than expected.
Underestimating SSML and voice tuning effort
Amazon Polly and Google Cloud Text-to-Speech rely on SSML and model or engine configuration that takes time to master, and outputs can sound off if setup and testing are skipped. Microsoft Azure AI Speech also depends on selecting the right voice and SSML configuration, so you need iteration before production rollout.
Choosing cloning when you actually need dataset-tuned custom voices
ElevenLabs, PlayHT, and Resemble AI focus on voice cloning from reference audio, so they are not the best match for speaker-level customization built from your dataset. Microsoft Azure AI Speech is the tool in this set that explicitly supports custom voice models tuned to your dataset for closer speaker consistency.
Expecting browser playback without engineering work for API-based tools
Amazon Polly can require engineering around API calls and audio handling for browser playback, so planning your integration matters early. iSpeech and Google Cloud Text-to-Speech also work primarily through API endpoints, so you need implementation time for app embedding and streaming patterns.
Ignoring cost scaling from long scripts and high-volume usage
ElevenLabs and PlayHT can rise quickly with long scripts and frequent revisions, which makes revision strategy a cost driver. Amazon Polly includes usage-based charges for synthesized characters, and Google Cloud Text-to-Speech costs scale with character volume and audio duration, so budgeting based only on the $8 baseline can break production forecasts.
