Before You Switch Voice Providers: Six Audit Prompts

Alibaba cut Qwen-Audio prices by up to 95% on 25 September and published no per-unit rates. ElevenLabs sits at $100 per million characters. A percentage is not a quote, and "up to" is doing real work in that sentence. These six prompts work out what you actually spend, what you would actually save, and what you would be giving up - before you move anything customer-facing.

1
What Am I Actually Spending, By Job
A 95% cut on ASR is worthless if 90% of your bill is TTS. This tells you which number to chase.
Here is my voice API billing for the last 90 days.<br/><br/>Split total spend into: text-to-speech, speech recognition, and realtime interaction. For each, give me characters or audio-minutes processed, spend, and effective rate.<br/><br/>Then tell me which single job accounts for the largest share of spend.<br/><br/>Do not give me an average across all three. The three have completely different price structures and a blended rate hides which one a migration would actually help.<br/><br/>BILLING:<br/>[paste]
2
Translate a Percentage Into a Number
"Up to 95%" is a range, not a rate. Model the floor before you plan around the ceiling.
A provider has announced price cuts of "up to 95%" on speech recognition, "about 70%" on text-to-speech, and "roughly 85%" on realtime, without publishing per-unit rates.<br/><br/>Using my usage profile below, build three scenarios:<br/>1. BEST CASE - the maximum advertised cut applies to my exact usage<br/>2. MID CASE - the midpoint of each range<br/>3. WORST CASE - the cut applies only to a tier I do not qualify for, so I pay the old rate<br/><br/>Give me monthly spend under each, and say which assumptions each scenario depends on.<br/><br/>USAGE:<br/>[paste]
3
Build the Quality Regression Test
Most migrations are decided on price and reversed on quality. Set the stop condition before you start.
I am evaluating a cheaper voice provider against my current one.<br/><br/>Design a blind A/B test I can actually run this week. Specify:<br/>1. How many samples, and how to choose them so they represent my real content rather than easy cases<br/>2. The specific failure modes to listen for in TTS - mispronounced proper nouns, wrong emphasis, unnatural pauses, emotional flatness<br/>3. For ASR, the error categories to count separately - proper nouns, numbers, domain terms, overlapping speech<br/>4. What result should stop the migration<br/><br/>Give me point 4 as a specific threshold, not a judgement call.<br/><br/>MY CONTENT TYPE:<br/>[paste]

Find the Switching Costs Nobody Budgets
The irreversible ones matter most. A cloned voice you cannot recreate on the new provider is a lock-in you paid to leave.
I am considering moving voice providers. From my setup below, list every cost of switching that is not the API rate.<br/><br/>Include: voice cloning or custom voice recreation, re-recording anything already published for consistency, SDK and integration rework, prompt or SSML rewriting, latency differences that change UX, data residency and compliance review, and the cost of running both in parallel during cutover.<br/><br/>For each, estimate whether it is one-time or ongoing, and flag anything that would be irreversible.<br/><br/>SETUP:<br/>[paste]
5
Check the Language and Dialect Fit
A split setup is often the right answer and almost nobody models it, because the comparison is framed as either-or.
Below is the list of languages and locales I publish in, with volume for each.<br/><br/>A candidate provider supports 16 languages plus 20 Chinese dialect regions. My current provider supports a broader set.<br/><br/>Tell me: what share of my volume the candidate covers, which locales I would lose, and whether a split setup - candidate for covered locales, incumbent for the rest - costs less than staying put once I account for running two integrations.<br/><br/>LOCALES AND VOLUME:<br/>[paste]

Price In the Next Repricing
Launch pricing is an acquisition strategy. Decide against the price you will pay in year two.
A voice provider has just cut prices steeply to win market share. A different provider in the same market raised prices 2.3x to 4.5x this year after establishing its position, and kept its customers.<br/><br/>Given my usage below, model what happens if the cheap provider raises prices by 3x in 18 months:<br/>1. My spend at the new rate<br/>2. Whether it is still cheaper than my current provider<br/>3. What it would cost me to migrate back at that point<br/><br/>Then tell me whether the migration still makes sense on a two-year view.<br/><br/>USAGE:<br/>[paste]
